Hello there from a newbie. I hope this is in the correct section. I have searched the forum but not found the information I need.

I have just purchased a 2000 Golf 2.0 convertible. Does this count as a mark 4? Or is it a mark 3½? Or a just a face-lifted mark 3?

It has aftermarket 17" OZ wheels which are not in great shape. They might be able to be refurnished, possibly.

I can't find out what the correct tyre and wheel size should be. I do not have an owner's handbook. I would like to return the car to a more original look.

One slight problem: I can't remove the centre caps to find out whether I have four stud or five stud hubs. I hope someone here can tell me. So before I take it to a garage and ask for the wheels to be removed (seller said they had also lost the locking wheel nut key! ), I want to purchase some wheels and tyres first. This way I won't be without a car.

Then I can sell the OZs. They might fetch a few quid but I'm not too worried about them.

Many thanks in advance for your knowledge.
