Once upon a time I did a lot of research on these and bought one:
Didn't think they did an M-TEC on the 328 (came along with the 330), also I thought the SE had chrome round the windows and kidney grill with the M3 style "bucket seats". Are you lucky enough to have the Harmen Karden button?
On the flip side, nice looking car and a good near enough 200 bhp rear wheel bit of fun
Nice car to chuck round corners sideways and fold flat rear seats so you can get a whole world of stuff in the back that you never thought possible!
