🚗 Should You Finance a Car Through the Dealership or Your Bank?

“Financing a car without comparing options is like accepting the first offer at a pawn shop — you probably left money on the table. 💰😬” - Chase Jordan

I'm reviewing this today because I still see people getting caught at the dealership over paying for financing a car.

When you buy a car, the dealership will almost always ask the same question:

“Do you plan to finance with us today?”

Seems simple enough.

But behind that question is a maze of markups, incentives, and hidden terms that can cost you thousands if you’re not careful.

As your car buying concierge and consumer advocate, Deal Guard is here to help you decode it all.

Let’s explore whether you should finance through the dealership or go with your own bank or credit union — and how to avoid getting burned.


🏦 What’s the Difference Between Dealer Financing and Bank Financing?

  • Bank or credit union financing: You apply directly and often get a straightforward rate based on your credit and loan term. No middlemen.

  • Dealer financing: The dealership acts as the middleman. They send your credit app to multiple lenders — then offer you a rate that may be higher than what the lender actually approved you for.

That extra margin is called a finance reserve, and it’s pure profit for the dealer.

So if a bank approves you for 6%, the dealer might offer you 7.5% or 8.2%— and pocket the difference as a commission over the life of the loan.


📈 Why Dealerships Push Their Own Financing

  • They earn money from marking up your rate

  • They may receive manufacturer incentives to close loans in-house

  • They control more of the deal (making it easier to bury costs in the monthly payment)

Some dealers even promise better discounts only if you finance through them.

This is a red flag unless you know exactly what you’re agreeing to.


😎 Why Your Bank or Credit Union Might Be Better

Here’s why we usually recommend getting pre-approved through your own lender:

  1. Lower rates — Credit unions especially tend to offer better APRs than dealer lenders.

  2. Transparency — No markups or surprises. What they quote is what you get.

  3. More control — You negotiate with confidence knowing what you’re approved for.

  4. Fewer tricks — Dealers can’t inflate your payment by sneaking in overpriced warranties or add-ons.

Plus, when you already have financing in hand, the dealership knows you’re not dependent on them.

That shifts the power dynamic in your favor.


💡 The Smart Way to Play It: Get Pre-Approved First

At Deal Guard, we guide our clients through this every day.

Here’s our proven strategy:

  1. Get pre-approved by your bank or credit union before shopping. Get 2-4 rates to know what is out there. It may take 1 hour to do this but it can save you hundreds if not thousands. Not bad for 1 hour's work!

  2. Let the dealer make their offer — and compare it to your best one.

  3. If the dealer beats your rate without added tricks, great! Take it.

  4. If not, you’ve already got backup financing ready to go.

Just make sure the dealer’s offer isn’t hiding - AKA read the fine print:

  • Longer loan terms to make payments look cheaper

  • Add-ons financed into the loan without clear explanation

  • Higher interest rates than your actual approval

This is where a car buying consultant steps in to help you break it all down.


🚨 Common Dealer Finance Pitfalls to Avoid

  • Accepting the first offer without comparison

  • Not asking for the lender’s "buy rate" (what they actually approved you for)

  • Financing overpriced extras like extended warranties or paint protection

  • Falling for monthly payment tricks — a low monthly payment can still mean a bad deal over time

At Deal Guard, we make sure none of this slips past you.


🧾 What About Special Financing Offers?

Sometimes manufacturers offer 0% or low APR deals, especially on new cars.
These can be legit and I've used them myself — but usually require excellent credit, short terms, and sometimes you lose out on rebates by choosing them. So do the math over the life of the loan. Do the rebates save you$1000 when the lower rate could save you $1700? Or vice versa?

We help you calculate the true cost of those options and compare them to real-world alternatives.


😎 Final Word from Chase

Financing can be the trickiest part of the car buying process — and also the most expensive if you get it wrong.

At GetDealGuard.com, our car buying concierge service makes sure you’re not overpaying by thousands in hidden finance charges.
