I hoestly don't recall Grissom's car being stolen, however Nick's truck was stolen in season 6's Rashomama and all the evidence that was crammed into it.
the episode wher grisom had to go to the county because there was a body in the ground with onlt the head shown and he had to go to the superstore to buy his crime scene kit (pencil lead etc...)
I don't remember Grissom's car being stolen, either. In Anatomy of a lye, they're outside looking at Ecklie's Mercedes, which Grissom had previously sold to him. That's all I can think of.
