9 Tips for Buying a Used Car

Opting to buy a used vehicle rather than the newest model on the lot can be a great way to save some money. Used cars often cost significantly less than new cars. In addition, older cars are generally cheaper to insure (since they are worth less than new cars).

The process of shopping for, and financing, a used car, however, can feel intimidating. To demystify the process, we’ve got nine simple strategies that can help you find a reliable used car that fits your lifestyle and budget.

Key Points

•   It’s a good idea to establish a budget before you start the used car buying process.

•   If you’ll need financing, consider getting preapproved for a car loan before you start shopping.

•   Researching the car’s history is essential to avoid potential issues.

•   Test driving the car and getting it inspected by a mechanic can also help you assess its condition.

•   Don’t be afraid to negotiate the price of a used car, as it can often lead to a better deal.

1. Setting a Budget for a Used Car

Before you start researching used cars, you may want to first think about how much you can afford to spend on a car and how you will pay for it.

If you will be paying cash, you may want to consider how much of your savings you can realistically put towards a car. If you don’t have quite enough, or the purchase would completely gouge your savings, you may want to spend a few more months saving up for a car.

If you will be getting a loan for the car, you’ll want to think about what would be a comfortable monthly payment. One rule of thumb is to put at least 10% down and finance the car for three years. You may also want to try to keep your total monthly auto expenses no higher than 20% of your monthly take home pay.

You can use an online auto loan calculator to get a rough idea of how much you might need to spend each month on financing.

2. Getting Financing Before You Start Shopping

If you plan to get a loan to buy the car, it can be a good idea to get preapproved for a car loan from a bank, credit union, or another lender before you start shopping.

While you may opt to go with financing offered by a car dealership, having a pre-approved car loan offer in your back pocket can give you a great negotiating tool. Dealers tend to mark up the interest rate to make a profit, but if you already have a deal in place, they will know they need to beat it in order to get your business.

Even if you’re going to buy a car through a private sale, having a pre-approved loan in place will allow you to jump on a great deal as soon as you find it.

3. Choosing Your Ideal Car

Now that you have a car buying budget in mind, you may want to look into what types of cars you can get for that money.

Do you need a truck, SUV, or sedan? You can save money outright by buying a smaller car and also down the line if it’s good on gas mileage. If safety is a top priority, you may want to check out the Insurance Institute for Highway Safety Ratings to see which cars perform the best in crash tests. You can also narrow the field by making a list of must-have features, and then searching for cars that have them using a search tool like Edmunds Car Finder.

Once, you’ve narrowed your list to three target models that you can research in more detail. You may also want to read reviews about the cars you’re interested in on sites like Kelley Blue Book and J.D. Power.

4. Shopping for a Used Car

Once you know how much you can spend and what kind of car is going to be a good fit for you, you can actually begin shopping for a used car. There’s no need to start driving to car lots all over town — you can browse through tons of vehicles online.

Good places to look include: used car superstores like Carmax or Carvana, used car dealerships, as well as new car dealerships (which often also sell used cars, though not always at the lowest prices). You may also want to look at listings from local private party sellers, which you can find on Craigslist, eBay Motors, Facebook Marketplace, and Nextdoor.com.

💡 Quick Tip: Are you paying pointless bank fees? Open a checking account with no account fees and avoid monthly charges (and likely earn a higher rate, too).

5. Researching the Car

Once you’ve pinpointed a vehicle you might want to buy, it can be a good idea to find out as much as you can about the vehicle’s history.

You can get a vehicle history report from a company like Carfax or Autocheck , which can tell you if the car has any red flags, such as reported accidents or flood damage, as well as information on the car’s maintenance and service history. To get a report, you’ll need to get the car’s vehicle identification number (VIN) or license plate number from the seller. There is typically a fee for running a report (around $25) but many dealers will provide the report for free.

You may also want to run the VIN number through the United States Department of Transportation Recalls site to check for any safety recalls. If there have been any recalls, it’s a good idea to make sure that the issue has been fixed.

6. Going for a Test Drive

It can often be helpful to try before you buy, especially when it comes to buying a car. A car dealership will typically let you take a few cars for a drive so you can get a sense of how they feel.

You may want to call ahead before visiting a dealership to make sure they have the car on the lot that you’re interested in so you can see it that day. A private seller will also likely allow you to take the car for a brief spin to see how you like it.

Some things to consider when going for a test drive:

•   How well the car accelerates and corners
•   If the breaks are responsive
•   If there are any unusual noises or vibrations that could indicate a mechanical issue
•   How well the car fits you — is there enough leg room? Can you comfortably reach all of the controls?

7. Inspecting a Used Car

Even if you’re far from a car expert, it can be a good idea to do a visual inspection of the car. Is the car’s body and paint in good shape? Are the lights all working? Are there signs of cracks or water inside the lights?

You may also want to turn on the air conditioning and heating, radio, and navigation system and make sure they are all working properly.

When examining the interior, you’ll want to make sure it is in decent condition and there aren’t any unpleasant smells — a moldy smell can indicate flood damage and cigarette smells can be hard to get rid of.

8. Getting a Mechanic to Inspect the Car

Unless you are buying a certified used car with factory warranty coverage from a dealership, you may want to consider getting a car you are close to buying inspected by an independent auto mechanic. While this does involve an investment of some cash (typically $100 to $200), it can potentially save you from dealing with a costly repair soon after you buy the car. The inspection report may also give you some bargaining power when haggling over the price of the car.

9. Negotiating the Price of a Used Car

It’s rare that you’re going to come across a used car price where the seller is unwilling to budge, even a little. Before you negotiate a car deal, however, you’ll want to have all your research ready, including how much the average make and model car for a particular year goes for, and any concerns or issues that came up during your personal and professional inspection.

If you’re negotiating with a dealer, it can be a good idea to keep the focus on total cost of the car, rather than bring a trade-in or financing into the mix. Dealers may want to merge all of the numbers into one deal, which can be confusing — and also make a not-so-good deal look better.

When discussing price at a dealership, you may also want to make sure you are talking about the out-the-door price, including all fees (so there aren’t any surprises).

The Takeaway

Buying a used car can be a smart buying decision. To make sure you get a car that suits your needs and budget, however, you’ll want to research your options, come up with a target price range, and line up financing before you shop.

When shopping for used cars, it’s a good idea to learn a car’s history, test drive the car, and also have it professionally inspected.

Knowing the value of the car in the open marketplace can help you negotiate a good price. If you don’t like the deal, there’s nothing wrong with walking away.

Qualifying accounts can even access their paycheck up to two days early.


Better banking is here with SoFi, NerdWallet’s 2024 winner for Best Checking Account Overall.* Enjoy up to 3.80% APY on SoFi Checking and Savings.



SoFi® Checking and Savings is offered through SoFi Bank, N.A. ©2025 SoFi Bank, N.A. All rights reserved. Member FDIC. Equal Housing Lender.
The SoFi Bank Debit Mastercard® is issued by SoFi Bank, N.A., pursuant to license by Mastercard International Incorporated and can be used everywhere Mastercard is accepted. Mastercard is a registered trademark, and the circles design is a trademark of Mastercard International Incorporated.


SoFi members with Eligible Direct Deposit activity can earn 3.80% annual percentage yield (APY) on savings balances (including Vaults) and 0.50% APY on checking balances. Eligible Direct Deposit means a recurring deposit of regular income to an account holder’s SoFi Checking or Savings account, including payroll, pension, or government benefit payments (e.g., Social Security), made by the account holder’s employer, payroll or benefits provider or government agency (“Eligible Direct Deposit”) via the Automated Clearing House (“ACH”) Network during a 30-day Evaluation Period (as defined below).

Although we do our best to recognize all Eligible Direct Deposits, a small number of employers, payroll providers, benefits providers, or government agencies do not designate payments as direct deposit. To ensure you're earning 3.80% APY, we encourage you to check your APY Details page the day after your Eligible Direct Deposit arrives. If your APY is not showing as 3.80%, contact us at 855-456-7634 with the details of your Eligible Direct Deposit. As long as SoFi Bank can validate those details, you will start earning 3.80% APY from the date you contact SoFi for the rest of the current 30-day Evaluation Period. You will also be eligible for 3.80% APY on future Eligible Direct Deposits, as long as SoFi Bank can validate them.

Deposits that are not from an employer, payroll, or benefits provider or government agency, including but not limited to check deposits, peer-to-peer transfers (e.g., transfers from PayPal, Venmo, etc.), merchant transactions (e.g., transactions from PayPal, Stripe, Square, etc.), and bank ACH funds transfers and wire transfers from external accounts, or are non-recurring in nature (e.g., IRS tax refunds), do not constitute Eligible Direct Deposit activity. There is no minimum Eligible Direct Deposit amount required to qualify for the stated interest rate. SoFi members with Eligible Direct Deposit are eligible for other SoFi Plus benefits.

As an alternative to Direct Deposit, SoFi members with Qualifying Deposits can earn 3.80% APY on savings balances (including Vaults) and 0.50% APY on checking balances. Qualifying Deposits means one or more deposits that, in the aggregate, are equal to or greater than $5,000 to an account holder’s SoFi Checking and Savings account (“Qualifying Deposits”) during a 30-day Evaluation Period (as defined below). Qualifying Deposits only include those deposits from the following eligible sources: (i) ACH transfers, (ii) inbound wire transfers, (iii) peer-to-peer transfers (i.e., external transfers from PayPal, Venmo, etc. and internal peer-to-peer transfers from a SoFi account belonging to another account holder), (iv) check deposits, (v) instant funding to your SoFi Bank Debit Card, (vi) push payments to your SoFi Bank Debit Card, and (vii) cash deposits. Qualifying Deposits do not include: (i) transfers between an account holder’s Checking account, Savings account, and/or Vaults; (ii) interest payments; (iii) bonuses issued by SoFi Bank or its affiliates; or (iv) credits, reversals, and refunds from SoFi Bank, N.A. (“SoFi Bank”) or from a merchant. SoFi members with Qualifying Deposits are not eligible for other SoFi Plus benefits.

SoFi Bank shall, in its sole discretion, assess each account holder’s Eligible Direct Deposit activity and Qualifying Deposits throughout each 30-Day Evaluation Period to determine the applicability of rates and may request additional documentation for verification of eligibility. The 30-Day Evaluation Period refers to the “Start Date” and “End Date” set forth on the APY Details page of your account, which comprises a period of 30 calendar days (the “30-Day Evaluation Period”). You can access the APY Details page at any time by logging into your SoFi account on the SoFi mobile app or SoFi website and selecting either (i) Banking > Savings > Current APY or (ii) Banking > Checking > Current APY. Upon receiving an Eligible Direct Deposit or receipt of $5,000 in Qualifying Deposits to your account, you will begin earning 3.80% APY on savings balances (including Vaults) and 0.50% on checking balances on or before the following calendar day. You will continue to earn these APYs for (i) the remainder of the current 30-Day Evaluation Period and through the end of the subsequent 30-Day Evaluation Period and (ii) any following 30-day Evaluation Periods during which SoFi Bank determines you to have Eligible Direct Deposit activity or $5,000 in Qualifying Deposits without interruption.

SoFi Bank reserves the right to grant a grace period to account holders following a change in Eligible Direct Deposit activity or Qualifying Deposits activity before adjusting rates. If SoFi Bank grants you a grace period, the dates for such grace period will be reflected on the APY Details page of your account. If SoFi Bank determines that you did not have Eligible Direct Deposit activity or $5,000 in Qualifying Deposits during the current 30-day Evaluation Period and, if applicable, the grace period, then you will begin earning the rates earned by account holders without either Eligible Direct Deposit or Qualifying Deposits until SoFi Bank recognizes Eligible Direct Deposit activity or receives $5,000 in Qualifying Deposits in a subsequent 30-Day Evaluation Period. For the avoidance of doubt, an account holder with both Eligible Direct Deposit activity and Qualifying Deposits will earn the rates earned by account holders with Eligible Direct Deposit.

Separately, SoFi members who enroll in SoFi Plus by paying the SoFi Plus Subscription Fee every 30 days can also earn 3.80% APY on savings balances (including Vaults) and 0.50% APY on checking balances. For additional details, see the SoFi Plus Terms and Conditions at https://www.sofi.com/terms-of-use/#plus.

Members without either Eligible Direct Deposit activity or Qualifying Deposits, as determined by SoFi Bank, during a 30-Day Evaluation Period and, if applicable, the grace period, or who do not enroll in SoFi Plus by paying the SoFi Plus Subscription Fee every 30 days, will earn 1.00% APY on savings balances (including Vaults) and 0.50% APY on checking balances.
