As a previous owner of a 335i, I have no regrets changing over to the 330d. I smoke them all the time. The 335i is no match for the launch of the 330d. It launches like its connected to a rubber band.I have flashed the tranny and a few other mods and my opponents with all this JB4 and cold air induction systems are always shocked to find out that they have been smoked by a DIESEL. I am now at 160,000km and never had a single issue. Great Buy to be had
