Don't know about that MPG John, my old 335d absolutely battered the previous 325ti in terms of economy & range when doing about 20k miles pa. On top of that the performance was very impressive, especially when overtaking (not just for a diesel!), and the car was almost "old school" GT-like in the way it would cover large distances effortlessly

Saying all that, I'll take a petrol engine every time for the fun stuff, even one that isn't as fast. But as a single car to cover all the bases then a 35d takes some beating
