Wouldn't touch them with the proverbial barge pole, however, look in AutoTrader at www.autotrader.co.uk or do a Google search to see if anyone is lurking around. Either way be sure that the vehicle has a FULL dealer service history and not from some local garage - these things have twitchy electrics and their gearboxes can also be fun. If you live near the sea it will probably last about three years before it is knackered.
Good luck!
