including the cambelt, the usual waterpump which is very important, good condition coolant hoses, otherwise its CHOD(coolant hose of death), the pipes that come from inside the car at the back of the engine bay, you can buy some kits which vary from £180+. is it the turbo coupe or no turbo ? if you are looking to buy the turbo model, as normal on a turbo car check to see if its been replaced or of course well looked after.
the standard manifolds on the 5 cylinder, presuming its the 5 cylinder youll be buying, they crack due to the design of the 5th exhaust port. its also a good thing to get one with a new clutch, as this can cost about £500+ from a specialist to replace.
i dont think ive covered everything here, but check out
http://www.fccuk.org/forum, im sure theres a ton more information on there.
theres alot of dogs out there, so try to avoid those coupes, personally id have a budget of £2000 for a standard coupe, specially if all the important jobs are done.
