We've had one since March last year and I can find no fault with it.
They were running a deal on contract hire at the time, so we have it for two years.
It's the 335d. 50mpg when the wife's driving but 313bhp too. The engine and gearbox are fabulous.
Boot is massive as is the rear cabin. No heated/electic seats as standard, which I was surprised at though.
As its a lease I wasn't about to start adding options.
My wife's cousin has the 435d GC and is equally impressed.
The only thing I didn't like was the run flat tyres so I swapped those for regular tyres.
Any specific questions, fire away!
