Question 1

Is it better to finance a car through a bank or dealership?

Accepted Answer

It depends on the current offers available. Dealer financing through the manufacturer's captive lender wins when promotional rates apply — 0% APR, 1.9%, or 2.9% subvented rates are common on new models and beat anything a bank can offer. Outside of promotional periods, your own bank or credit union typically offers a lower rate than the dealer's marked-up rate. The best strategy is to get pre-approved from your bank before visiting the dealer, then let the dealer try to beat your rate.

Question 2

What is a pre-approval for a car loan?

Accepted Answer

A pre-approval is a conditional loan offer from a bank or credit union stating the rate, amount, and terms they will lend you before you select a vehicle. Getting pre-approved before visiting a dealer gives you a rate benchmark, removes time pressure from the financing decision, and serves as negotiating leverage. Most pre-approvals are valid for 30–60 days and require a hard credit inquiry. Shopping multiple lenders within a 14-day window counts as a single inquiry for scoring purposes.

Question 3

Do credit unions offer better car loan rates than banks?

Accepted Answer

Generally yes. Credit unions are member-owned non-profits and typically offer auto loan rates 0.5%–2.0% lower than traditional banks for comparable credit profiles. On a $30,000 loan over 60 months, a 1.5% rate difference saves approximately $1,200 in total interest. Credit union membership requirements have loosened — many now accept members who live or work in a county or who join an affiliated association for a small fee.

Question 4

How does dealer financing markup work?

Accepted Answer

When you finance through a dealer, the dealer submits your application to multiple lenders who respond with their buy rate — the lowest rate they will accept for your credit. The dealer can then mark up this rate (add percentage points) as profit called the dealer reserve. You see only the final offered rate. A 1.5% markup on a $30,000 loan over 60 months represents approximately $1,200 in extra interest paid to the dealer. Having a competing pre-approval prevents this or eliminates it.

Question 5

When should I use dealer financing instead of my own bank?

Accepted Answer

Use dealer financing when: 1) A manufacturer promotional rate (0%, 1.9%, 2.9%) applies to your vehicle — these beat any bank rate; 2) You are buying a CPO vehicle with a manufacturer-subvented CPO rate; 3) The dealer beats your pre-approval rate after negotiation; 4) You need approval quickly and the dealer's lender is more flexible. Never use dealer financing by default — always get pre-approved first so you have a benchmark.

Scenario	Why Dealer Wins
0% APR promotional offer	Manufacturer subsidizes rate; impossible for bank to beat
Subvented rate (1.9%, 2.9%)	Below market rate from captive lender on specific models
CPO vehicle with manufacturer financing	CPO programs often include subvented rates
Dealer beats your pre-approval	You got a pre-approval and the dealer matched or beat it

Scenario	Why Bank/Credit Union Wins
No promotional rate on your vehicle	Standard dealer rate includes markup; bank is cheaper
High credit score + established credit union relationship	CU rates often 1–2% below dealer standard market rates
You want rate transparency before negotiating	Pre-approval gives you certainty the dealer cannot change
Buying from a private party	Dealer financing not available; bank/CU is the only option

Financing Source	Typical APR Range (New)	Typical APR Range (Used)
Manufacturer captive (standard)	5.5%–8.0% (including markup)	7.0%–10.0%

National bank (Chase, Wells, BofA)	5.5%–8.5%	6.5%–9.5%
