Haha, good stuff man. A deal is a deal, so make the best of it!
$45 from the dealer really isn't bad, you won't get one of the same quality for much less than $35 off ebay.
I haven't seen too many E46's in that colour with a lot of work on them, but if I ever see any I'll send them your way. Good luck with the wheel hunt. Just please stay well away from chrome... haha. Tint would also look good, and funny enough with that colour, you could go light or dark and it would still look good.
