Forgetting your budget

While used cars offer a more budget-friendly alternative to new vehicles, they still require a financial investment. To determine your affordability, consider your monthly income and budget.

One recommendation is to make sure your car payment isn’t more than 10% to 20% of your monthly income, so keep that in mind when estimating how much you can afford.

Not having financing lined up

You don’t have to rely on a dealership to finance your loan, and it may be more affordable for you to shop around and find the best car loan terms before you decide on a car.

Contact your bank or financial institution and see the loan and terms they would approve. It will give you a better idea of what you can afford and also give you pre-approval to make the buying process easier.

Skipping the research

Take a moment to define your specific needs. Are you prioritizing fuel efficiency, safety features, or ample cargo space? By pinpointing your must-haves, you can quickly narrow down your options.

This focused approach will save you time, energy, and money, allowing you to find the perfect vehicle for your lifestyle.

Resolve $10,000 or more of your debt

Credit card debt is suffocating. It constantly weighs on your mind and controls every choice you make. You can end up emotionally and even physically drained from it. And even though you make regular payments, it feels like you can never make any progress because of the interest.

Forgetting the extra costs

Your monthly car payment isn’t the only cost you have to consider as a car owner; you’ll also want to factor in other costs like maintenance and potential repair costs.

Consider how many miles per gallon a particular car gets, for example, as fewer miles per gallon means you’ll need to pay more for gas.

Focusing only on the monthly payment

Some car loans offer a higher interest rate for a longer period of time, helping you lower your monthly payment.

It’s important to calculate not only your monthly payments but also how much you’ll pay for the entire length of the loan terms. You may be surprised that you’d pay more because of accumulating interest over more years.

Skipping an independent inspection

Used cars may have specific issues or additional wear and tear from their previous owners, so it’s important to know what’s going on under the hood of your vehicle before you buy it.

You may want to get an independent inspection done by a trained mechanic or other inspector to make sure the vehicle is in proper running order and doesn’t have issues that could lead to costly repairs and maintenance once you’re the owner.

Not getting a history report

Before it comes to you, a used car has a history with previous owners. Do you know what that history includes?

You can find out by running a history report through companies like Carfax and AutoCheck that can show you if the car had major mechanical issues or was in an accident before you decide to buy.

Skipping the test drive

You won’t know how a car drives until you actually drive it, so get behind the wheel and see how it operates before committing to it.

Consider issues like whether the car accelerates properly, feels comfortable to drive, or makes noises that could indicate something brewing under the hood.

Not researching the seller

You’ll be buying a used car from either a dealer or a private party, so take some time to research the seller before you commit to buying a vehicle.

You may want to look for customer reviews for a dealer or ask for references from a private seller to ensure their trustworthiness.
