About Car Deal Checker
Shopping for a used car? Car Deal Checker tells you if the price is fair before you ever talk to a dealer. Open any listing and get a deal score out of 100, the real out-the-door price with tax and dealer fees included, and your true monthly payment, right on the page. No copying numbers into a car payment calculator, and no switching tabs.

COMMON QUESTIONS
Is this used car overpriced? The deal score compares the listing price against similar cars and the car's own history, then shows its work.
What will this car really cost me? The out-the-door number adds tax, title, and dealer fees to the sticker price, and the payment is figured from your numbers, not the dealer's.
Can I check for recalls and accidents? Yes. Every listing gets a VIN decode, an open recall check from NHTSA, and red flags for accident history and salvage titles.
PRIVACY
No account, no ads, no tracking. Your settings and saved cars stay in your browser. The extension only contacts NHTSA and the EPA for vehicle data, and Gumroad to check a Pro license key. Full policy: swensondigital.carrd.co
