yeah if it's done 80,000+ miles ask if it's had a clutch, and ask for proof, if it hasn't youre looking @ £350 if you have to get a garage to do it, same goes for the cam belt, that's another £150+ for a garage to change it,
also seen a few on ebay with the head gaskets gone @ 100k + so check for water in the oil, oil in the water, unless you know what your doing walk away
