Yep, Dave, I totally agree with you! Thats why I'm not even making a slightly lower offer, they look worth it, and as you say, will probably sell for similar when the time comes around.
The link was put up as an example of the wheels in question as I couldn't find another picture and didn't know their name. I have a set I can get a lot cheaper.
The whole idea is because I have a set of winter tyres on the alloys from my old Mk4 Golf. I was hoping to use the tyres this year instead of selling them on. So I was after a set of alloys that fit the tyres AND clear the brembos. Then I was gonna refurb the 18" multispokes that are on there now.
I don't fancy squeezing the wrong centre bore (although its only 1mm smaller) onto the alfa over winter so the old alloys (Audi TT Ronals) are a no go. Seems these one I was hoping to use are too.
I have a couple offers now to try similar wheels on the car so will see what works in my meagre budget! Sounds like sticking to what I have on now and sell the winter tyres is where its heading!
