Thanks again Guys.
Actually, I think the police acted pretty quickly really; they called just after 8 this morning and a 'scene of crime' van met me at the garage by 11 (I couldn't get ther earlier). They dusted where they could, but the bu**ers had wiped her down pretty well. They found glove marks so said unfortunately they knew what they were after; they could have taken a lot more actually. They left no prints on the CDs they left (obviously not to their taste!), but the police took the 2 tonne jack that they left under one side (log under the other), so you never know, might get something from that. Got some blood from one of the wing mirrors, which they had folded in! The police thought it probably would come back as having 6 legs (dead insect) rather than 2 unfortunately, but they took swabs anyway! Overall I was pretty impressed, and they really did seem sympathetic.
