I brought 7 cars from Copart this past summer. Only 2 of them have gone as expected.
2016 GMC Sierra SLT HD Duramax - wheel fell off because someone decided to not only swap out the factory chrome wheels for base WT steelies, they also left 6/8 lug nuts off the front wheels and put the lug caps back on. Wheel falls off on the highway lol. Still haven't gotten into it yet but I'm sure I'll find some surprises.
2016 Porsche Cayenne. Moderate front end damage in pictures. Get the car only to find out the driver knee airbag was deployed but hidden in the pictures. Car was listed run & drive but the accident shifted the subframe a hair and cracked the block where the motor mount connects. I paid over half of clean retail to get the car after fees, NOT including replacement parts, only to find out I need a new engine block because cast iron is a PITA to weld. Nobody's selling blocks for a 16 cayenne and complete engines are 10k+. At the end of this ordeal it would cost close to what a CLEAN retail Cayenne costs.
