I am entitled to my opinions and I always stand by them. The Z3 interior was always a bit of a disappointment to me because it looks so minimalist and ugly...until the new 7, 5, 3, and Z4, all of the BMW interiors have never been anything special to me. The Z4 interior has much more of a "true roadster" look and feel IMO, and I love the aluminum trim.
I am sticking to my opinions about the E90 and iDrive. The E90 330i Sport, according to Edmunds.com, slaloms exactly as fast as the E46 M3 (which makes it more sporty than the E46 3-Series) and I do believe the iDrive, as well as the new 3-Series, are great. Just look at Acura, Audi, and Infinti...they have all adopted their own version of BMW's iDrive.
I wish the people who actually AGREED with me would chime in when these debates come up (HINT, HINT, YOU KNOW WHO YOU ARE). Either way, I don't mind standing alone on the issue.
