LOL no you didn't do anything wrong! Best keep an eye on ebay or have a search around on here - there's a few places that sell refurbed genuine BMW alloys, possibly your best bet although the 108-style alloys do come up on ebay infrequently (I've yet to see a set of the 107 ellipsoid alloys though).
I was trying (but failing) to have a dig at Paisley, i.e. bricks for wheels, when asking about your wheels . I feel entitled to as I spent enough time there when I was younger...
