That's a good price range to be in, we have a couple of options that would work for your car. I know you said you want to stick with 18s but I'd really encourage you to step up to 19s. 18s IMO are far too small for the E90-E93 and it's really not worth it to change the wheels if you are sticking with the same size. I will give you a few options (CSLs, M6s and M5s are available in 18" and 19").
