Did you see any noticeable marks on the ground when it was stolen? Skid marks, scrapes that would have been left by chains/jacks, anything? I ask because a few years ago a friend's del Sol got stolen, and the way they got it was they jacked it up in the center (there's a solid spot on the radiator support you can jack from), slid a 2 wheel dolly under it, then cut the rear brake lines so the e-Brake was no longer a factor.

Good luck getting her back!
