Somebody posted BMW's 2007 CARB certifications. No 325i and 330i submitted for 2007, but 2 new models - 323i and 328i. The 335i is a sure thing as per BMW's announcement, but was probably a separate CARB submission. Anyways, all very confusing and full of speculation. I'm not sure it's going to help you, but it sheds light on the upcoming model line.
Seems to be a consensus that the 2007 model line is 323/328/335.
One thing caught my eye - a 2007 328ix sports wagon with a reputated 235 HP - a possible wish list car when gas goes to $4.00.
