I'd never condone insurance fraud, but ADZ's idea sounds pretty promising to me. My advice would be to remove the brake disks / pads, radiator, wiper motors, cat converter, fuel pumps, power steering pump etc before signing it over, they Ebay the lot.
Otherwise, here's a heartwarming tale courtesy of a friend of mine who got royally screwed over.
He bought a Japanese import Nissan Pulsar GTI-R a few years back but was moving abroad so decided to sell it. His mechanic also had a business selling cars and suggested he buy the Pulsar off my mate for £1100, explaining that because of the amount of Japanese performance cars imported into Britain the bottom had fallen out of the market and as he knew my mate he'd make a generous cash offer.
Two days later the Pulsar was up on a forecourt for £5,000. My mate was royally pissed until the phone rang:
Mechanic: "Erm, thought you should know that your Pulsar was stolen from my forecourt last night. You didn't have an immobilizer fitted did you?"
(note, a good number of Japanese imports don't meet the usual European security standards and require further modification after import. My mate lived in a relatively safe area and neglected to get this done).
Mate: "No."
Mechanic: "Well, seeing as I bought it thinking it was immobilised and have lost out on the sale, can I have my money back?"
Mate: "Get f*cked" (puts phone down).
:lol:
