Mistakes to Avoid When Buying Your First Car

This lesson is general education about U.S. personal finance, not financial, tax or investment advice. Tax rules and limits change every year; check IRS.gov or a qualified professional for your situation.

Buying your first car mixes excitement with paperwork, and the paperwork is where money gets lost. The mistakes below show up again and again, from how people budget for the purchase to the checks they skip before signing. Each one has a fix you can handle before you ever set foot on a lot.

Skipping the Total-Cost Picture

The sticker price is only one line in the cost of owning a car. The Federal Trade Commission advises shoppers to think through the kind of car they need, how they will use it, and their budget before shopping, and to account for the ongoing expenses that come with any car, such as registration, insurance, fuel, and upkeep. Two cars with similar prices can cost very different amounts to keep on the road.

Research the models on your list as well: repair records, safety test results, and typical mileage. A car that costs a little more up front but carries cheaper insurance and better fuel economy can come out ahead over a full year of driving.

Before you shop, work the monthly cost of ownership into your budget. If you set aside a fixed amount from each paycheck to cover the payment, gas, insurance, and upkeep, you will know what you can actually afford. Getting started with paying yourself first shows how to make saving automatic so the fund is ready when the right car appears.

Financing at the Dealership First

Walking into a dealership without a financing plan means accepting whatever rate is put in front of you. You can arrange a loan through a bank or credit union, or finance through the dealer. Getting prequalified with one or two outside lenders before you visit gives you a benchmark, so you can tell whether the dealer’s offer is competitive or whether you should keep shopping.

Your credit history shapes the rates you are offered, so it helps to know where you stand before you apply. If you are still working on building a credit file, our article on whether paying rent builds credit explains what actually counts.

Watch out

Be careful with companies that promise to negotiate lower payments on your car loan if you pay them an advance fee. The FTC warns about these auto loan refinancing offers, and an upfront fee for a promised result is a red flag.

Shopping Only for the Monthly Payment

A payment you can barely stretch to make feels affordable in the moment, but the loan term behind it decides what the car really costs. Stretching a loan over more years lowers the monthly figure and raises the total interest you pay, and it raises the odds that you owe more than the car is worth if you sell or trade it early. Ask for the total price and the total cost of financing, not just the monthly number.

The FTC also recommends asking dealers for out-the-door prices in writing before you visit. Those written quotes let you check that advertised prices, discounts, and rebates actually make it onto the paperwork, confirm the car is really on the lot, and catch extra charges that appear only once you are sitting at the desk.

Ignoring Insurance Before You Buy

You generally need insurance in place before you drive the car home, and lenders usually require coverage on a financed car. Waiting until the day of purchase means accepting the first quote you find, on a car you have already committed to.

Premiums vary a lot from model to model, so get quotes on the exact vehicle before you sign anything. Our first car insurance quote checklist walks through what to gather before you request quotes, so the numbers you compare are accurate. If a model’s premium surprises you, that is useful information while you can still walk away and pick a different car.

Skipping the Vehicle History Report

Before you commit to any used car, the FTC advises pulling its history report first. The National Motor Vehicle Title Information System, at vehiclehistory.gov, lists approved providers of these reports. You enter the VIN, the vehicle identification number, and pay the provider’s fee, which can run up to $4 per report. The report includes title, insurance loss, and salvage information.

Two free checks are worth adding. The National Insurance Crime Bureau keeps a database where a VIN search can show whether a car was damaged in a flood, stolen and never recovered, or written off as salvage. And the National Highway Traffic Safety Administration’s website lists vehicles subject to open safety recalls, meaning the manufacturer has recalled the car but the repair has not been done. Enter the VIN to check, or call the Vehicle Safety Hotline at 1-888-327-4236.

Skipping the Inspection and the Buyers Guide

A report cannot take the place of an inspection by a mechanic you choose, since some damage never shows up in any report. Have that mechanic look over any used car before you buy, even if the dealer has certified it. You pay the inspection fee, but it can save you from a car with major problems. Ask for the maintenance records from the seller, and test drive the car over hills, at highway speed, and in slow traffic. If the odometer works out to more than 20,000 miles a year or fewer than 5,000, ask the seller why.

Dealers must display a Buyers Guide on every used car they offer for sale. It tells you whether the dealer is selling the car with no warranty coverage at all or standing behind it, how much of the repair bill the dealer would pay under that warranty, and it lists the major mechanical and electrical systems along with some of the problems to look out for. It also reminds you to get an independent inspection before you buy. The copy you receive at the sale becomes part of the sales contract and overrides contract terms that conflict with it, so keep yours. Maine and Wisconsin use their own state versions of the form.

Buying online changes one thing in your favor: for online sales, dealers must give you the option to cancel your order and get a prompt refund when the car does not ship on time. The FTC has taken enforcement action against an online seller that failed to provide required Buyers Guides and delivery refunds, so the rules have teeth.

Falling for Last-Minute Add-Ons

Add-ons are extras the dealer pitches during the sale, usually products or services you did not come in asking for, and they tend to appear late in the process, once you are tired and ready to finish. Written out-the-door quotes requested before your visit are your best defense: any charge that appears at the desk but not in the quote should be questioned. Ask whether each add-on is required to qualify for the financing, and whether it duplicates protection you already have elsewhere. If you do not want it, say so and watch that it comes off the paperwork.

Forgetting Taxes, Fees and Registration

The price on the window is not the amount you will pay. Sales tax, title fees, registration, and dealer fees all land on top of it, and the amounts vary by state, so check your state motor vehicle agency’s website for the rules where you live.

When you compare dealers, compare the out-the-door figure, which rolls all of these costs in. A dealer who will not give you that number in writing has told you something useful. Budget for the full amount rather than the sticker price, so the final paperwork does not wreck a deal you had already counted on paying for.

Common questions

What is an out-the-door price?

It is the total you would pay to drive the car home, including taxes, title, registration and dealer fees rolled in. The Federal Trade Commission recommends asking dealers for this figure in writing before you visit, so you can compare dealers and catch charges that appear only in the final paperwork.

Do I still need an inspection if the used car is certified by the dealer?

Yes. The FTC advises an independent inspection even when a dealer has certified or checked over the car. You cover the inspection fee, but that cost is small next to repairing major problems.

How do I check whether a used car has an open recall?

Enter the vehicle identification number on the National Highway Traffic Safety Administration’s website, which lists vehicles with open safety recalls. You can also call the agency’s Vehicle Safety Hotline at 1-888-327-4236.

Why is shopping by monthly payment a mistake?

A long loan term lowers the payment but raises the total interest you pay, and it raises the odds you owe more than the car is worth if you sell early. Compare the total price and total cost of financing instead.
