7th X5 
2011 BMW X5 Diesel xDrive35d 4dr SUV AWD (3.0L 6cyl Turbodiesel 6A)
2011 refinements perfect the X5
 Just took delivery of my 7th X5 after trading a 2009 35d for a 2011 35d. I loved the 2009 diesel, but road, exhaust, and engine noise were a little too intrusive. BMW refined the 2011 to reduce the "bad" noises while keeping "good" noise like the sporty grumble during acceleration. The suspension also seems to have been improved. It's subtle and the X5 is certainly not Lexus quiet, but I immediately noticed the difference: a more refined luxury feel. Press releases talk about new styling and engines, but not the improved suspension and noise reduction. That's a shame because those improvements address the only significant flaw in my previous X5. Good job BMW, you were listening.
