I had my 19J Ninety stolen off my driveway, but I was naive enough to assume it was a nice area, and it was safe. Never seen it again, and it was un-insured too, so I got fook all for it.
Also had my Carlton GSI 3000 stolen off my driveway (different house) despite a disklock and factory immobiliser, but got that back 2 days later, all be it with a smashed front wing.
