 To the point; I am a professional driver-driving instructor. Have owned too many cars to count-mostly high performance; Porsches, Bmw's, Audis.Bought this vehicle for size to transport my baby gandchildren. In 16k miles had to have the front brakes/rotors replaced 3 times.Sticking throttle never repaired. Very unsafe. Numerous electonics failures-over 20 times in the shop. Unable to repair the vehicle properly, including the sticking throttle. When I requested a trade assist for another model, M-B corp. refused-advised "thats whet the warranty is for". Obviously will never own another M-B
