 This vehicle is amazing! I have the 50i M-Sport w/ 20inch staggered wheels. My previous vehicle was an 2011 BMW 550xi M-Sport. All I have to say with comparing the two is the X5 feels quicker and handles better then the sedan. If you enjoy driving your vehicle like a sports car then you have to option the Dynamic Handling Package. This package makes this vehicle feel like its a 3series. Makes this huge suv very nimble in the corners it's worth every penny. I also love the quality in the interior BMW has come along way with there interiors. Especially with the Mocha Nappa Interior gives the vehicle a very rich feel. I love this SUV in my opinion I don't think there is anything else out there for the price that compares to the X5 for performance, comfort, handling, & safety. I would recommend this SUV everybody!
