What body style is he after in a 3 series , I assume a Coupe if he is coming from a VXR. The saloon would probably be a bit cheaper than Coupe but over here in NI any 335d is pretty hard to find.
Not out of the question I might be selling my E92 335d , Jan 07 with 36k miles and plenty of nice toys. Would need to stretch his budget a bit for it though but worth it, the 335d engine is superb and yes on paper not that much faster than a 330d but the twin turbo just makes it soooo effortlessly fast and if you do put in a bit of effort then it must be very fast !!!
