The trouble is most of the cars (Z3/Z4) with the exception of M's are worth more stripped. I still have the entire chassis/monocoque, running gear, engine/gearbox, Elec roof, windscreen, suspension, brakes, and roll hoops from the Z3, on which my "Italian Clothes" are draped.
The base Z3 2.8 cost me £2250 and I have sold the body panels and interior for £2000 so far (net cost of Z3 £250) with another £700 plus still listed for sale. If I did not need all the running gear mentioned above, that would be worth £1000 (conservatively). Grand total if I stripped and sold for parts £3950. £1700 profit!
The £1700 potential above does not include breaking parts down further than whole items. Pair of seats for example fetched £150, broken down into covers, runners, motors, switches, etc. probably £250.
Don't get me wrong, I would not advocate buying Z's just to strip, otherwise, I would be doing it wholesale (I have a well-equiped workshop and 30000 square feet of storage at my place). The cars are an appreciating asset that will realize more than a "quick-buck" profit over the next few years and, more importantly, are for driving pleasure not profit. As I said once before on here:
"Tax-efficient Stock Market is for Investment, houses are for living in, wine is for drinking, antiques are for sitting on and, Z's are for driving!"
