I treated myself to a 330d last August, and I have to say I’m still in love with it.
I average around 43mpg during the week on the commute to work which is 18 miles each way, mostly A road with far too many roundabouts to be enjoyable. To be honest it’s more than quick enough, but if I really wanted to I could get it put on a rolling road and have power increased to over 300bhp.
It’s a special edition which is I believe at 273bhp.
I would ask myself how much mileage do you do and what type of roads, not sure I’d bother with a 335d.
Oh mine is a coupe which I have now fitted a removable towbar to, and have a Thule towbar mounted rack for biking duties.
