Wow, came out to 45,100!! The 335i I configured was only 48,000. I think the only real reason to get a 135i would be if you plan on turning it into a track car and don't get any options on the car, then you could keep the price around 35k. But once you add some of the things that would make it a nice daily driver like leather/nav/ipod those type of things it just skyrockets.
