VW ?

depends how much your wanting to spend the dealers can be a bit of a rip off. tried scrap yards? its only a lever so can proberbly get it cheep (or put it down trousers and say they didnt have the part you need

not promoting steeling though

) doesent exactly need to be new as its a lever, they dont exactly get used a great deal can safely say ive only touched mine 3 times since ive bought the car.
or ebay, im not sure on which lever you mean thought ( the one to move the seat backwards and forward or the one to tilt it back and forth so someone can get in the back? ) but ive just searched on ebay for mk4 golf seat leavers and a few came up.
