Lets clear up a bit of confusion here....
The PCD on the golf 3 VR6 is 5x100, the PCD on the Audi 200 is 5x112.
The offset on both are near enough the same.
It is possible to make/buy an adaptor that converts 5x100 to 5x112 BUT to allow room for the bolts to fit in the adaptor will be 20mm+ thick. This will obviously push the wheels further out in the wheel arch by 20mm+. If you want to go for the fatter EURO look then this is good but it may cause the wheels to rub. The other issue is caliper clearance but the 20mm+ thick adaptors should negate this problem.
