What to Bring When Buying a Car: A Simple Checklist

The documents to bring when you buy a used car in Illinois, from your driver's license and insurance to proof of income and your trade-in title, so you can drive home the same day.

Quick answer: Bring your driver's license, proof of auto insurance, and your down payment. If you're financing, also bring recent pay stubs and a proof of address such as a utility bill. If you're trading in a car, bring its title if it is paid off, the registration, and every key. If you still owe money on it, we call your lender for the payoff.

Having your paperwork ready is the easiest way to make buying a car quick. If you have everything with you, the visit is mostly the test drive and signing. If something is missing, you may have to come back another day. Here's what to bring, and why each item matters.

The short checklist

Bring thisWhy it's needed
Valid driver's licenseTo test drive, and to confirm who is buying
Proof of auto insuranceIllinois requires insurance before you drive away
Down paymentCash, cashier's check, debit card, or credit card
Proof of incomeOnly if you're financing
Proof of addressOnly if you're financing
Trade-in title and keysOnly if you're trading in a car

1. A valid driver's license

You'll need it for the test drive, and it's how the paperwork identifies you. If you're buying with a co-buyer or co-signer, they need to bring theirs too, and they should come with you to sign.

2. Proof of auto insurance

Illinois law requires liability insurance on every car on the road, so you'll need coverage before you drive your new car home. Many buyers call their agent from the dealership to add the car once they've picked one. Have your insurance card, your insurer's app, or your agent's phone number ready.

If you're financing, the lender will usually also want comprehensive and collision coverage until the loan is paid off. Ask your agent for a quote before you visit, so the cost doesn't surprise you.

3. Your down payment

At Carselect you can pay your down payment with cash, a cashier's check, a debit card, or a credit card. A larger down payment lowers your monthly payment and can help with approval if your credit is rebuilding. Our car payment calculator shows how much difference it makes.

4. Proof of income (if you're financing)

Lenders want to see that the payment fits your income. Bring:

If you've already applied online, the finance team will tell you exactly which of these your lender needs.

5. Proof of address (if you're financing)

A recent utility bill, bank statement, or lease with your name and current address. It should match the address on your application. If your license shows an old address, this document is especially important.

6. If you're trading in a car

Frequently Asked Questions

Can I buy a car without a driver's license?

You may be able to purchase a car, but you can't test drive it or legally drive it home. A licensed driver will need to drive it for you, and you'll still need insurance on it. Call us first if this is your situation.

Do I need insurance before I buy the car?

You need it before you drive the car off the lot. You don't need a policy on that specific car ahead of time. Most insurers can add a new car with a phone call or in their app once you have the vehicle's details.

What if I don't have pay stubs?

Bank statements showing regular deposits, a tax return, or an income letter can often work instead. Every lender is different, so tell the finance team what you have and they'll find out what's accepted.

Can someone else's name be on the loan with mine?

Yes. A co-buyer or co-signer can strengthen an application. They need to bring their own license and proof of income, and they should be there to sign.

Should I bring my trade-in even if I'm not sure I'll trade it?

Yes. Bringing the car and its paperwork lets us give you a real offer, and you can decide once you see the numbers.
