i'm guessing target audience, similar stats / price / engine hp etc.. I drove a g35s before buying the 335i, and there are lots of little things and some things you cant put your finger on that make the bmw special, the g35 just didnt feel special. For some 8-10k is a lot, heck thats what some peoples car costs. So in then end it's what you like, and what you can afford. I still cant understand why people buy pickup trucks, or mini vans...but that is just me.
