Car Buying
Protection Checklist

The dealer does this every day. You do it once every few years. Here is what they know that you should too — before you sign anything.

New Cars

Used Cars

Certified Pre-Owned

Lemon Law Reference

⚠️ The average car purchase is $48,000 new, $28,000 used. These checks take 30 minutes and most cost nothing.

Before You Leave Home — Research

Do not skip

Strong advantage

Good to know

For New Car Buyers

Know the invoice price — not just the MSRP

MSRP is the manufacturer's suggested retail price. Invoice is what the dealer paid. The gap between them is your starting negotiating room. Sites like Edmunds and TrueCar publish invoice prices for most vehicles.

Big Advantage

Look up dealer holdback and current factory incentives

Manufacturers pay dealers a holdback — typically 2–3% of MSRP — just for selling the car, separate from your negotiation. Factory rebates and incentive cash belong to the buyer, not the dealer. Know what's available before you walk in.

Know This

Check for ADM (Additional Dealer Markup) on the sticker

On high-demand vehicles, dealers add a market adjustment above MSRP. This is negotiable — especially as inventory normalizes. Never treat ADM as a fixed cost.

Watch For It

Check for open recalls at nhtsa.gov/recalls

Free, takes 60 seconds. Even new vehicles can have open recalls. Dealers are required to fix recalls on new cars before delivery — know if one exists before you take possession.

Required

For Used & CPO Car Buyers

Run the VIN before you visit

Any legitimate seller will give you the VIN upfront. If they won't — that's your answer. Check title history, accidents, and whether it's been through auction. A VinPassed report shows all of this plus what the dealer paid.

Required

Know what the dealer paid at auction

Dealers often buy at auction for 30–50% less than their asking price. Knowing their cost tells you exactly how much room exists. That number is your real negotiating ceiling.

Big Advantage

Check for open recalls at nhtsa.gov/recalls

Dealers are not required to fix open recalls before selling a used car. You could be buying a known safety issue they're legally allowed to sell you.

Required

"Certified Pre-Owned" means inspected — not clean history

CPO means the dealer looked at it. It does not mean it has no accident history, no auction records, or no title issues. Always verify independently with a vehicle history report.

Understand This

For All Buyers

Know the market value from at least 3 sources

KBB, Edmunds, and NADA often differ by thousands. A VinPassed report includes 12 market value data points. Dealers cite whichever number supports their asking price — know all of them before you walk in.

Smart Move

Get pre-approved for financing before you go

Your bank or credit union will give you a rate to beat. Without a baseline, you have no way to know whether the dealer's financing is competitive. This matters more than most buyers realize — see Section 3.

Important

At the Lot — What to Inspect

Check panel gaps and paint consistency

Uneven gaps between body panels or mismatched paint sheen — even subtle texture differences — are signs of repaired collision damage that may not appear on any report.

Don't Skip

Look under carpet and in the trunk for water damage

Flood cars are cleaned and resold regularly. Check for musty smell, stained carpet backing, rust on the spare tire well, or corrosion on wiring under the dash.

Don't Skip

Verify all VIN plates match

The VIN on the dashboard (visible through windshield), door jamb sticker, and engine block should all match exactly. Any scratches, misalignment, or inconsistency is a serious concern.

Check It

Test every electronic feature yourself

Windows, locks, infotainment, backup camera, heated seats, sunroof. Warning lights can be reset before a sale. If something is broken now, it won't show up in any history report.

Check It

Request an independent pre-purchase inspection (used only)

A mechanic of your choosing — not the dealer's — for $100–150. Any dealer who refuses is telling you something. This is your last defense against mechanical issues no report can catch.

The Finance Office — Where the Real Negotiation Happens

The finance manager controls three things simultaneously: the price, the loan term, and the interest rate. You control one thing: the monthly payment you're willing to make. That information gap is why this room matters more than the lot. Go in knowing the math.

Negotiate the out-the-door price first — payment is a result, not a starting point

Once you agree to negotiate on monthly payment, the dealer controls everything else. They can adjust the term and rate to make any price hit your number. Agree on total price first, then discuss financing.

Critical

Know your interest rate — and who set it

Dealers source financing from lenders and are often allowed to mark up the rate — sometimes 2–3 points — and keep the difference. Your pre-approval from a bank or credit union is the number they need to beat. Without it, you have no baseline.

Critical

Calculate the real cost of every add-on — not the monthly cost

When a finance manager absorbs an add-on by extending your loan term rather than raising your payment, the actual cost is far larger than it appears. Here is the real math:

Example: "Only $20 more a month" with a term extension from 60 to 66 months

Original loan $500 × 60 months = $30,000

With add-on (term extended to 66 months) $520 × 66 months = $34,320

6 extra months at original payment $500 × 6 = $3,000

$20 increase paid over the full new term $20 × 66 = $1,320

Total additional cost $4,320 — not "$20 a month"

This does not include additional interest on the higher financed balance over the longer term, which increases the real cost further. Every add-on they present carries this same math behind it.

Critical

Read every line of the contract before signing

Add-on products — paint protection, gap insurance, tire warranty, extended service contracts — are sometimes added without a direct ask. Each is a separate profit center. Cross out anything you didn't explicitly agree to.

Do This

Ask these before you sign anything

→ "What is the total loan term in months?"

→ "What is the total amount financed?"

→ "What is my interest rate, and is that the lender's rate or has it been marked up?"

→ "If I remove this product, show me the new payment AND the new loan term — both numbers."

→ "What is the out-the-door total if I pay cash today?"
