i have a 335d e92-would rather drive an m3 though lol wonderful package particularly dct and its a quicker car if you use the rev range
the following stops me from buying
335d-£220 a year to tax m3 £500 a year
335d 40 plus mpg m3 18mpg or less

service/repair costs on m3 also very high in comparison-its a bit more sophisticated

no cost involvement it would be the m3 anyday-but being a tight git its the oil burner for me
