Not that you'll here much disuasion here, but "do it"!
I've wanted an E90 M3 ever since their introduction in 2008. Thats the only body style I wanted (personal preference) however I wasn't in a position to afford it back then. Now as the E90's end of production draws nearer, I have decided to jump on the bandwagon and intend on keeping the M3 indefinately.
I was able to factory order mine as well-wouldn't have had it any other way for a long-term purchase, and despite the special order, was able to get a healthy discount too. Get in before you can't get 'em any more!
