I guess everyone has an opinion on why they went with BMW and continue to stick with them. My hobby is to drive... so before BMW I had a G35 that handled the canyons nicely. I next upgraded to a 06 325, that car handled with such incredible balance I was blown away. My next purchase was an "IS"... the perfect blend for canyons and a night on the town. Sure Porsche is superior, but no back seats was a deal breaker for me.
I can never understand the complaints on the BMW interiors, simple and classy in my opinion. Its supposed to be a drivers car, right?
