Depends on what you're talking about. CTF cars yes. IVERs, no.

CTF cars are more or less production cars that GM employees drive and report any problems so they can fix them before retail production begins. Once the test period is over, they're cleaned up and retrofitted with any updates and auctioned off.

IVERs are engineering cars that must be crushed at the end of the program. A lot of them are cobbled together (interiors are sometimes duct taped together) and GM can't risk the liability.
