I have never owned a diesel anything before and I wanted try one out.
My wife and I had been looking at the new Passat TDI for a run around car. It seemed nice and roomy and fair priced. We likely would have bought it had I not stopped at the BMW dealer. So we bought the 335d. Granted it is not a fair to compare as there is about a 17-20K delta. The Passat had more space for sure but is was just a car (as in boring to drive). In any case we have put 2700 miles in a month and so far we love it.
It has good power for passing or jumping on the freeway. This one has the M-sport package which also comes with paddle shifters. It is kind of delayed and just slushes into gear so those are kind of goofy. I think BMW wants to be sure that your not down shifting inplace of up shifting. A manual transmission behind this twin turbo charged engine would be even funner. The 335d has only been stateside for two years and they only offer the automatic as of now. I read there is a BMW tuner that is now selling a hand held that improves the RWHP by 60 HP, but I have a 100K warranty that covers everything but the tires so I likely will not mess with and enjoy it for what it is a commuter car. The 425 FT Lbs @ 1750 RPM kinda of shocks you. It handles nice, quiet and gets 36MPG.

It is my understanding the most Diesel #2 comes from the same source and only some formulating is done by the refinery. Has anybody noticed problems and or changes buying diesel say from Arco vs. Shell or is it all the same? I never realized they had multiple size Diesel fuel nozzles. I pulled into a gas station the other day and the nozzle would not fit but the car came with an adpater.
Here is a pick of the car
