For this sort of money it's a mistake to go for something that originally cost £50,000+ because all the problems will be £50,000 car problems, not £5000 car problems. If you buy from a trader he will almost inevitably have at least £2000 profit in the car so you'll be paying £5000 for what cost him £3000, but he will be liable for any fault that develops during the fist six months. My advice would be to buy a Nissan Terrano II or a Mitsubishi Shogun.
