Quick answer

With dealer financing, the dealer sends your application to lenders and arranges the loan. The CFPB explains that the lender may approve you at a buy rate, and the dealer can offer you a higher contract rate and keep part of the difference (often called dealer markup or dealer reserve). A bank or credit union loan is arranged directly with the lender. Getting pre-approved directly gives you a rate to compare and negotiate with.

How dealer-arranged financing works

The dealer collects your application and shops it to banks, finance companies or the manufacturer's captive lender. The CFPB explains that the rate a lender is willing to give you is the buy rate, and the dealer may be able to set a higher rate on your contract; that markup is compensation to the dealer. You can ask what the buy rate is and negotiate the rate.

Direct lending: banks, credit unions, online lenders

You apply directly and get an approval with a rate, term and maximum amount. You can then shop for the car like a cash buyer. Credit unions require membership, which is often easy to qualify for.

Comparison

	Dealer-arranged	Direct (bank / credit union / online)
Convenience	One stop	Apply ahead of time
Promotional rates	Manufacturer offers sometimes available	Usually not
Rate markup	Possible	No dealer markup
Add-on pressure	Add-ons often offered in the finance office	Less, though lenders may offer GAP

Best practice: use both

Get pre-approved directly (several applications within the CFPB's 14 to 45-day shopping window generally count as one inquiry).
Negotiate the car's out-the-door price.
Then let the dealer try to beat your pre-approved APR on the same term.
Pick the offer with the lowest total cost, and decline add-ons you don't want. The FTC says optional add-ons must truly be optional.

Frequently asked questions

What is a buy rate?

The CFPB defines it as the interest rate at which a lender is willing to finance your loan through the dealer. The dealer may offer you a higher rate and keep part of the difference.

Can I negotiate the interest rate at a dealership?

Yes. Rates arranged by dealers may include markup, so a competing pre-approval from a bank or credit union gives you leverage.

Are manufacturer 0% offers real?

They can be, but often require excellent credit or replace a cash rebate. Compare the total cost of the promotional rate against the rebate plus outside financing.
