Hi all, I have stumbled across a 1983 635 csi in Spain. It has had new wings, radiator , tyres and brakes overhauled and been regularly serviced. It is a UK car, righthand drive, but has not been driven for 8 years. It does start and idles ok, but Icannot road test it. There is one tiny bit of rust on the rear wheel arch, and that appears on a quick look to be all. It has a dateless registration plate too. I have been offered it for 400 believe it or not. The owner is returning to the UK and wont take it back with him. What areas should I be looking at for problems and should I buy it? My plan is to restore it. Thanks, Tiddy
