First of all, I would like to introduce myself to this great forum. I am located in Miami Florida and I just purchased a 2008 E70 X5 for my wife. We had a 2006 Infiniti QX56 which we sold for the X5. I really liked the QX 56, but the wife always wanted the X5, so end of story. So far, it's been 2 weeks of ownership and so far it has been better than I expected, The ride and quality of this vehicle is superior in all ways compared to the QX56. As for the X5, we went with the 3.0 due to gas prices and the vehicle price as well. I found it hard to swallow an extra 15 to 20K for the 4.8, and they look the same. We went with the premium package, 3rd row seating, tech. and rear climate package, white with tobacco interior. Paid 53K. The one thing I had to change and fast, were the wheels. I really hated those stock 18" wheels, they did nothing for the car making it look more like an X3. So I ordered the 214 replicas, which have a polished face and painted inside, unlike the all painted OEM wheels. As for tires, went with the michelins latitudes. Looks much better and rides the same as the aweful runflats. As for the fender flares, still not sure if I should replace them, we'll see. In closing, I would like to thank all of you that post valuable information on this post, it helped me greatly in my purchase and now in some mods.
