The standard version of 2011 x5 worked well for me because I didn't want roof rails, didn't want running boards, prefer the leatherette for cleaning purposes, and knew I was going to change the wheels out soon - and the price was great.
Took delivery a couple weeks back but wanted to make a few minor mods before posting any pics. Finally found a local guy with the 300M x6m reps and put them on today. Makes a huge difference from those 18"ers.
Changes are: Painted Reflectors (IND), Titanium Grill, Window Tint (35% complete), Debadged the side (not sure about the back yet), added fender flares front and back, and of course the 300m's.
Love the ride so far, coming from a 3 series but starting a family now so this gives me a lot more room and handles amazingly well.
