I've owned the E70 in the diesel, old six, and current 35i.

I love the 35i. Totally different vehicle than the 2010 normal six was. I also like the updated look and iDrive. All well worth it in my opinion. Put the 35i in the tranny sport mode and the thing is amazing.

I'm not a diesel guy, the idle rattle and lag didn't work for me. But the diesel is also a great option and I respect those who like it. Completely personal preference.

The new Jeep looks nice (as does the Explorer). I'm going to drive both soon (love driving new cars). Jeep scares me a bit being first year and a radical redesign. Still great to see competition to keep BMW honest.
