Just rode for first time in a 325. I assume the 328 is the upgrade. I found the 325 to be a lot smaller than I thought, and if the 328 is about the same size, then I better find another car to look for. I live in a small town, and so have yet to visit the nearest bmw dealership for eyeball and test drives. Please tell me the 328 is larger, inside and out. Thank you.
