What the photos don’t show
Sellers only photograph what looks good. We flag what they skipped: missing odometer readings, missing engine bay shots, concealed rust zones, and underside damage.

Open the PDF on your phone, or print it. Last page is a checklist for the driveway. If the seller won’t go to a shop, don’t buy it.
The expensive failure points
Every model year has known mechanical failure points that cost thousands. We translate technical jargon into plain English with real shop estimates so a cheap car that needs $4,000 of work is obvious.
Fair price & seller tactics
An estimated fair-price range in USD so you never overpay. Estimated state sales tax and registration reality. Plus, straight answers to common seller tactics: pre-warmed engines, fake urgency, and “just needs freon”.
Then take it to an independent shop with a lift.
Over 70% of catastrophic used-car defects (subframe rust, transmission fluid leaks, suspension rot) are completely invisible from the driveway. Our report prepares you with the right questions, then points you toward an independent shop with a lift when we’ve confirmed one in your city.
Pre-Purchase Inspection
Independent Shop Inspection
The briefing provides your homework, pricing valuation, and driveway checklist. An independent shop inspection confirms frame and mechanical integrity before you hand over cash.
Pay the shop directly · Not included in this briefing
IsThisCarOK is independent homework. Pay a licensed shop before you buy.
Common questions
Clear answers on buying a used car from a private party.
Why is buying from a private seller riskier than a dealer?
Dealers are bound by state licensing laws and mandatory disclosures. Private-party sales are typically as-is with zero warranties. If the engine fails five minutes after purchase, the cost is entirely yours.
Is this report a substitute for Carfax or a vehicle history report?
No. A vehicle history report tracks past reported accidents, title branding, and registrations. We don’t sell history reports. Buy Carfax yourself if you want one.
What if the seller refuses to let a mechanic inspect the vehicle?
That is an immediate dealbreaker. Legitimate private sellers with nothing to hide welcome an independent pre-purchase inspection on a lift. If they refuse, walk away immediately.
Don’t gamble thousands on a used car.
