Buying a used car somewhere else?

Know what you are buying before you pay

Bring a private-party, auction, online-listing, or another-dealer vehicle to our Frederick shop. In about 1.5–2 hours we scan, road-test, photograph, and hand you a Green / Yellow / Red written report — so you can walk away or negotiate with facts.

  • Scan, road test, and photos — not a walk-around guess
  • Shop printout plus a branded digital report
  • Standard passenger vehicles $199; European, diesel, EV, or modified quoted before we start
Book the $199 inspection

Battery-electric inventory when we have it

Tesla, Polestar, and other battery-electric vehicles carry the same One Time Price as every listing. Hybrids and plug-in hybrids are on a separate page so you are not shopping the wrong list. Shop work on EVs is tires, rotations, brakes, and alignments — we do not advertise high-voltage battery or drivetrain repair.
