FYI there's some really good deals out there for rims today for Black Friday. I just ordered some replica CSL 18" from **********s for $499 a set! Going to put some Blizzaks on them for the winter.
Will post pics once I get them.
There area lot of forum sponsors out there with really good specials, check out the sponsor area in the 3series forums since nothing is really targeted at the x3.
