@Whipcity - remember i don't know your budget and was recommending a budget approach ... because i know the factory alloys are very affordable. yes, the 13" were an option on the 2002 ... but i don't think they had the chrome hub covers, which makes a difference. no question that alpinas on the e9 are great. the only other wheel i like as much is the bbs rs. if you want more 'bling' then i recommend the bbs rs ... a lot more expensive. one other option you may want to consider, you can buy a set of coupeking alpinas and have the lip polished.
if you can find the original trim rings and caps in great condition, that would be great. if you were reconditioning an old set, my condition is that you will spend between 500 and bucks +/- 250. i remember when i bought my new set for the bavaria - i spent 160 bucks for everything. i hope you can find a nice set.
