I dont think anything exterior will match up with a gen 1. I was thinking you meant like performance mods, suspension... etc. When i bought my 2007 speed 3 all i could find was the CBM, and i wanted black or silver. (ended up with black) i know they are out there, somewhere. But you probably wont find many on this forum cause a lot of guys and gals have gen 2's on here.
I really thought the sideskirts would mate up (MS3 vs MZ3 2007-2009). When I bought my car (used) the guy that owned it had a passenger side blind spot (already replaced the fog, strut, control arm.
All that's left is the sideskirt (been looking for almost 2 years now). The dealer wants $580 for this piece painted, which isn't TOO bad but I don't have it and it's not a mechanical piece so it's been on hold.
No, not looking for any performance pieces from a Gen2 OR a MZ3.
