With 118K miles and no body damage or mechanical issues, this would probably be a $23K car. If it had 70K miles it'd be closer to $30K. Mileage is definitely on the high side for an M Coupe.

This one has significant body damage that will require repairing, replacing and painting most or all of the body panels. How much would that cost? $5-10K? More?

Plus undercarriage damage and unknown mechanical issues like overheating? I'm sorry, but this is a tough sell. It'd probably cost $20K or more to make this car right (hence why it was on Copart), and that's just not worth it on a 118K mile example. You might consider parting it out. The value is in the drivetrain and parts, even with the mileage.
