They can be money pits - make sure the garage gives you a GOOD warrantee. Mines just turned 42k miles, and needed a £4k gearbox rebuild, and has had 2 clutches (£1.1k each fitted), front and rear brakes (£1.2k for discs and pads fitted), 40k miles service(£1.1k with cambelt), tyres (about £650 for 4 michelin PS2s). If it needs a turbo, which isn't unheard of, both are replaced at the same time, 'cause the engine has to come out (big job).

Get the reg number, and ask if anyone on www.rs246.com knows anything about this particular car, or if there is a good one for sale elsewhere.
