Still got the scoob and will never sell it, but needed car for work.
Brought an M3 CS SMG . 2006 with 19k on the clock
CS is the limited run of the club sport, it has the CSL bigger brakes 360mm, and suspension, also quick Rack and a track mode button on the steering wheel, which basically makes a few changes to engine response and SMG settings.
In my opinion with very limit experiance of an M3 the quick rack is by far the best thing on the CS.
Will get some pics up once i collect it.

And before all the comments about BMW drivers, i have had a 320M sport for 2 years so heard them all before. lol
