One other consideration... if you are thinking about an M3....I recall reading somewhere that M3s require more maintenance than the everyday 335. If this dealership is falling short on maintaining your D how are they going to do with an M3?
I'm definitely getting things documented next time in. At my rate of driving, 5K miles will come and go in 1-2 months. My rear brakes are telling me I need a change in 1700 miles and my job transfer doesn't come until Nov-Dec, so any potential car change is 4 months out minimum.

Regarding the maintenance, with the new job I should be okay using the dealer for standard maintenance while under warranty for 4 years. The M3 doesn't necessarily require difficult maintenance, just more maintenance, whereas the dealers seem to have no clue regarding these diesel engines. I actually like the idea of having a S65 that I can take to specialists near where I live to work on and do maintenance in between what is covered by BMW's maintenance schedule. I'm stuck with the dealer as my only option for the 335d because none of the shops have much experience with that engine.

We'll see. I look at this as two different issues. I want to get my 335d dealt with and fixed. That will take priority over my next couple visits. After that is dealt with, and if the finances work out on the deal, then I'll get excited about a potential move to an M3.
