Generally carburation, starter motor, master cylinder, clutch master and rear slaves.
Most of the problems were due to the car standing in my yard for a year and a half.
My Skoda has been lowered so it handles great on corners. The engine - I would give top marks for acceleration and economy, the car is very easy to service and very cheap as well.
I rebuilt the starter motor for £0.10 (the electricity to run the drill).
What kit did you use to lower your Skoda?
