The lease on my 2007 4.8 is up in a few months and it is time to think about my next car.

I've been doing a lot of research and thinking and I keep coming back to the X5. But the question is which one?

I've pretty much ruled out the Diesel. I think it is an awesome option, but I just don't want to deal with the hassle of finding diesel stations, and I have heard that there is some lag. I also don't want to get into significantly less performance than I have with my 4.8

So right now it's between the new 50, M, and the new 35

From what I've been reading the new 35 has performance characteristics that are similar to the current 4.8, but with better fuel efficiency

The 50 would give me even more power than my current 4.8 with about the same fuel efficiency that I have right now

The M would be insane

To be honest I think it will come down to the 35 vs the 50. The 50 is not that far off the M and is a more practical with 19s in the snow (I know all seasons are not substitute for snow tires, but I've had great results with my current setup when driving to Tahoe). But then again that M...

I will of course test drive the various models, but thought it would be fun to post a poll to see what other thought.

So which model would you pick and why?
