 I have been driving 750iX for 4 months now.The vehicle is solidly built. For those who are interested in purchasing one, following might be ofconcern;1. Throttle response on normal mode is below average. I feel it's hesitant to push forward and there is jerky feeling in the process2. The car gets quite noisy in over 80 mph both from tires and wind. Mine is equipped with all season run flat tires and that could be the reason3. When I shut off the engine, the radio (or ipod) still continues to be on. I have to press the start button one more time to shut off the radio and this is annoying4. I have to get really close to the garage door to open or to close
