Thanks for all the info, everybody! This definitely cleared all of my confusion!

I think, if I do decide to go the SAV route when the decision time comes, it will be between the X5 35d and X6 i35. I've driven a few SUV's - Lexuses, ML's, Ranges - nothing compares to BMW handling. I kinda like the idea of the Touareg V10 diesel, but they are getting old, and new ones have a 3L diesel that is, no doubt, inferior to BMW. Maaaaaaybe the G Wagen, but it is a totally different category vehicle altogether, plus way too expensive for my wallet.

Richard, good to see you on here! You still have the E60?
