Pretty much everything :)
Complete engine overhaul including piston rings, big-end bearings, valve guides. You name it...
Automatic choke is broken.
Clutch recently expired, but to be expected given the high mileage.
I bought the car from a man on a grass verge. His name wasn't even on the registration document. Everything turned out OK in the end though.
The engine is superb now. It pulls like anything in second gear and can out-accelerate our recent BMW 318i.
Motorway cruising is fun however fifth gear, given the designation "E", seems a bit feeble. Dropping into fourth is the only way to accelerate in the outside lane.
Brakes seem to be fine although the pipes will need replacement for the MOT.
Handling is good with typical FWD oversteer. I recommend a decent set of front tyres.
Interior has cleaned up very well and seems hard-wearing and comfortable.
Bodywork OK. Slight rust, but more a function of the way the car has been treated in the past I think.
VW parts are quite expensive. I could have got a better car had I spent another few hundred pounds. However it's running very well now and I am proud as well as pleased with it.
