It stinks when your vehicle gets stolen.
However ( call me a jerk if you like )... your friend is probably better off NOT getting it back. I assume that he has insurance?
The last time my vehicle was stolen, I got it back, but it had been beaten up ( it was a 4X4 ). My insurance didnt cover anything because we couldnt prove that the tranny & suspension DIDNT make those noises before the theft.
I ended up selling it at a loss.
Another case: My GMC Typhoon was stolen, & totaled in a high speed chase by the police. In that case the insurance covered it, but try finding another Typhoon to replace it...
I some cases, you are better off never seeing your car again.
