The conventional wisdom is that most cars are stolen for parts, which is why Hondas and Camrys top the list (the one car I had stolen wound up without engine and stereo). I wouldn't think there's much of a market for black-market RRC parts. 'hope it was just a joyrider and he'll get it back.
The upside is the extra needles included with the return of the truck. Although when our Honda Civic was stolen back in '98, it was found with an extra bag of pure change worth about $20, and a new set of tire chains that are a perfect fit for our 2008 Mercedes GL, I used them this weekend.
