the parts for my 90q were considerably more than what they would be for my integra. you’ve been in the vw/audi world for a long time (i believe), so you probably have a lot better sources for your parts.
i agree with your statement about how the car looks even with age. my 90q looked great for it’s age. there was absolutely no rust on the 13yr old car. the only problem with mine was the clearcoat was covered in spider cracks.
