[335dxdrive]

I can't see how buying a 340i would be a good move to myself

Less grip driving around and the way I chuck cars around I'd prob loose the back end in no time.

I also do about 15-17k per year, my 335d only averages 30 mpg with my heavy foot and mixed roads / mixed driving. A 340i would do way less thAN 30mpg with me.
