Definitely a big difference performance wise although I wouldn't say 325ci was lacking as it was just as fun to drive and fuel consumption was the same between the two.
Can't wait for an M3 as I expect it to be a complete hooligan a˜a
Thanks Jim, believe me when I say it is a head Turner and is cheaper to insure than my other 330ci m sport however time to sell them both and look for an M3
