I don't see any reason at all. The 328 is a bit of a step up engine wise but the 335 is pretty much the same shit with a new body slapped on to it. The interior in the F30 is pretty nice but nothing to go WOW about and the body doesn't really stand out like the E90 did when it first came out. I rather wait and see how the F32 plays out by then I'll be ready to upgrade anyway.
You can detect right away those that are going to be shaky, and that will fall behind and those that are very hungry, and that hunger you will have to develop. You gotta create a goal for yourself whatever that may be, a short term goal and a long term goal and you gotta go after that. And if you donít see it, and if you donít believe it, who else will?
