This is a great car - when it runs. The engine is very strong but the electrical system is very unreliable. You will get to know the MB service dept. well. Moreover, this is a fancy car and many mechanics are not trained to fix it's problems. Find a good mechanic and get the extended warranty!
So far this has been a terrific car. The power is unlike any vehicle I've ever driven. Believe everything you have read about this car; it boogies. The interior is different for me, having had SUV's and trucks. Cupholders and basic storage are the only downside. The build quality overall is impressive as is the overall comfort of driving. The driving experience is somewhat different because the brakes, gas pedal, and tranny are always "thinking" on how I am driving, etc, so it will take getting used to. It does drink the premium though. Also, the a/c is incredible, as in hang meat in the cabin cold. Stereo is OK...lots of gadgets overall. It's a beauty to look at too, makes me smile.
Nanananana... I've got one & the rest of the world is jealous. This is the real zoom zoom. Fastest car I've ever driven. Passengers noice the speed. Steering is as good as an EVO. Acceleration is somewhat violent and obnoxious as is the speed leveling, but still worth the effort & the money.
Have been enjoying my beast for 16 months and it is just as much fun to drive as when it was new. Just spent about $10K to get more power from this exotic 4 door. With basic ECU/Pulley and Headers I have close to 600HP and 650 Torque. This car runs 1/4 mile times in the 11's. What a great car to own and mod when you get bored with the stock power.
