Because of the cheap bicycle grade sprocket used on the Kompressor supercharged engine caused the tooth to grind down prematurely, eventually causing the drive chain to jump the tooth on the sprocket and destroys the engine at about 93,000 miles. This car is the worst car and most expensive car to maintain I have ever had! Mercedes you SUCK! You should refund me $7,000.00 for the car the was blown up and brand new almost. The outrageous cost to replace the engine was $7500.00 - $10,000 ! ! !

Your faulty manufacturing on these vehicles should compensate the owners a descent amount of money for this problem! I will never recommend this car or ever purchase another Mercedes Benz.
