RE: Cat D cars
Good buys/can be if repaired properly but only if your mate is planning on keeping it for a while. You may save a lot of cash but they are harder to sell unless it cheap, you only save on the intial cost of the vehicle. It will still depreciate and also be harder to sell.
I heard of an 04 plate m3 last week that went for Â£15k. That was cat d and had a dodgy history, Â£10k cheaper though... I considered it myself but decided not to get involved.
