How to Buy a Car, Step by Step: From Budget to Driving Home

Buying a car goes well when you make the decisions in the right order and at home, not at a desk in the showroom. Here is the whole process as twelve steps. Each one links to a deeper guide if you want it. Most people can do steps 1 to 8 over a week or two of evenings, and steps 9 to 12 in a single visit.

The short checklist

1. Set a total monthly budget.
2. Check your credit and get preapproved.
3. Decide new, used, or certified.
4. Build a shortlist of two or three models.
5. Find real cars and real prices.
6. Test drive.
7. Value your trade-in separately.
8. Get out-the-door quotes in writing.
9. Inspect the specific car.
10. Agree the deal and confirm it by email.
11. Get through the finance office.
12. Take delivery.

Before you shop

1. Set a total monthly budget

Start with what the car will cost you each month in total: payment, insurance, fuel or charging, and a set-aside for maintenance. The payment alone is the number a salesperson will ask about, and it is the least useful one. How much car can you afford walks through the math, and total cost of ownership covers the costs people forget.

2. Check your credit and get preapproved

Pull your credit reports and fix any errors first. Then apply for a loan with a bank or credit union before you visit a dealer. The Federal Trade Commission (FTC) puts the benefit simply: with a preapproval you know your terms before you shop.

A preapproval does not commit you to that lender. It gives you a rate to compare against whatever the dealer offers. The CFPB notes that loan applications made within a short window, 14 to 45 days depending on the scoring model, are counted as a single inquiry, so do your rate shopping in a couple of weeks.

3. Decide new, used, or certified

Each has an honest case. New gives you a full warranty and often the best financing offers. Used costs less up front and someone else has absorbed the early depreciation. Certified pre-owned sits between. New vs. used vs. CPO has a decision table. If you are also weighing a lease, read lease vs. buy.

4. Build a shortlist

Pick two or three models that fit your needs, then choose the trim. Being open to more than one model, and more than one color, is the cheapest negotiating advantage you will ever have. See how to choose a trim level. Check crash ratings and open recalls for the model years you are considering: checking recalls before you buy.

Shopping

5. Find real cars and real prices

Search live dealer listings for your shortlist within a distance you are willing to drive. For each car, note the advertised price, how long it has been listed, and whether the price has dropped. Three to five comparable cars at different dealers tell you what the market price is far better than any single sticker. How to read a dealer listing explains the fine print, and MSRP, invoice, and market price explains which number matters.

6. Test drive

Drive each finalist on roads you use: highway, rough pavement, your own parking situation. Bring the people and the car seats that will ride in it. Tell the salesperson up front that you are test driving today and not buying today. That is a normal thing to say. Checklist in how to test drive a car.

7. Value your trade-in separately

If you have a car to trade, get two or three written offers for it from other buyers before you discuss it with the selling dealer. Then you know its value and can treat it as a separate transaction. See trade-in value: how to get more and sell or trade in. If you owe more than the car is worth, read negative equity before you go further.

Making the deal

8. Get out-the-door quotes in writing

Email several dealers that have the car you want and ask each for an itemized out-the-door price: the selling price plus every fee, tax, and charge. The FTC recommends getting this in writing before you visit, and notes that your bargaining power is greatest before you go to the lot.

Compare the quotes line by line. Ask the dealers who are higher whether they can do better. The templates are in how to negotiate car price by email. To check a dealer's math, use the out-the-door calculator.

While you compare, look for:

• Fees you do not recognize. Dealer fees explained sorts the normal from the negotiable.
• Pre-installed extras. Dealer add-ons: worth it?
• A markup over sticker on a new car. Dealer markups and market adjustments
• Rebates you qualify for, and ones you do not. Rebates and incentives explained

9. Inspect the specific car

For a used car, get a vehicle history report and pay an independent mechanic to look at it before you commit. The FTC advises an inspection even when the dealer has certified the car, and suggests going elsewhere if a dealer will not allow one. See pre-purchase inspection and vehicle history reports explained.

For a new car, confirm the VIN on the car matches your quote, and check the window sticker for the options you are paying for.

10. Agree the deal and confirm it by email

Before you drive over, send one last message: the VIN, the out-the-door total, the fact that you are declining add-ons unless listed, and your appointment time. Ask for a reply confirming it. If you have a preapproval, say you will consider dealer financing if it beats your rate.

Signing and delivery

11. Get through the finance office

The finance manager prepares the contract and offers optional products such as service contracts and GAP coverage. These are optional, and you can say no to all of them. Compare the buyer's order and the contract to your written quote, line by line, before you sign. The finance office: what to expect and how to read a buyer's order cover each page.

Two things to know before you sign:

• Federal law does not give you three days to cancel a car purchase. Some states or dealers offer a return right; ask and get it in writing.
• If any number differs from your quote, stop and ask. If it is not fixed, you can leave. When to walk away from a car deal explains how.

12. Take delivery

Walk around the car in daylight. Check for damage, both keys, the owner's manual, floor mats, and any accessories you paid for. On a used car, make sure you receive the Buyers Guide, which dealers must display and give to you. Leave with signed copies of everything, and confirm how and when the title and registration will be handled: car sales tax, title, and registration.

The three rules that matter most

If you remember nothing else:

1. One number. Negotiate the out-the-door price, not the monthly payment.
2. In writing. A quote that exists only in conversation is not a quote.
3. Willing to leave. There is almost always another car like this one.
