if i were a car theif i wouldnt come onto a forum to locate and steal a flash car - I'd go on Auto Trader or ebay, contact the seller, say "i'm interested in the car, can i have your address please to come and see it?" - i'd scan the joint out a couple of nights see where the car is, what security it's got....then i'd make it dissapear.
Disclaimer - I am NOT a car theif, nor have i ever stolen a car before, nor will i ever steal a car.
