Welcome, and that’s a minty Avant to be sure. I love that you went OE on the wheels. On Ebay, I’ve noticed two things.
Ebay.de and Ebay.co.uk are less overrun by people listing a tidal wave of imported crap that has little to nothing to do with your vintage Audi search term (for me “Audi 4000”). I tend to watch them separately, and my username works over there.
I have noticed that Ebay.com is starting to see some people shifting back to it as a useful platform, and so the “real person” (or at least vendor) selling used and NOS parts ratio is going up. That’s good to see for sure.
