I had an Aero 8 S3 that I bought second hand wheel that looks quite similar (although I have been told the manufacturer of later wheels is different...)

This was quite badly curbed all round and not really as described before I bought it unseen for £115. I suppose the price was fair.

Brands Hatch Morgans had the wheel reconditioned for me for about £100 and it now looks as good as now - and is a spare which I'll be keeping until I need it! Meanwhile I avoid kerbs like the plague!! I don't know where they sent it but I'm sure they can remember. It was only last year...

Failing that a mobile service might be able to help but I don't think the stainless rims are easy to fix this way (just a guess).

Good luck!
