I think that if anyone were serious about stealing a Delorean, they would just quietly back up with a roll-back trailer and tow the thing away with a cover over it. I've had the thought go through my mind about installing a 'Lever-Lock' (tm). Once installed, you press the brakes all the way down and then flip this lever. It stops the brake fluid from coming back into the master cylinder until the lever is flipped back again. I installed one on an old motor home years ago because the parking brake on it was of poor design. One of these systems installed on the Delorean would lock all 4 wheels. I don't think anyone would tow one very far with that installed. Does anyone recommend Lo-jack? Walt Tampa, FL
