⚠️ Don't Buy A Lemon
A $6,000 Mistake: Just today, a buyer drove over an hour to Hudson for a car that looked perfect. Because they skipped the inspection, the engine blew up just a few miles down the road. They lost $6,000 instantly. We are here to make sure you aren't next.
Most inspection services (like Lemon Squad) just look at a car while it sits in a driveway. That is not enough.
Our process includes a 30-minute stress test on the nearest interstate. We push the vehicle to highway speeds to find overheating, transmission slips, and hidden engine knocks. We make sure the seller hasn't used "anti-knock" additives to temporarily mask a failing engine.
