 I purchased this used from a MB dealer with only 35000 miles. The moment I left the dealership, I started having problems with shaking, idling rough. It took 3 visits to the MB dealer in Florida before they corrected the problem. I have had this car in the shop so many times I lost count. Everything goes wrong with this piece of junk: Electrical system, door locks, instrument computer, door handle fell off, gaskets, seals, wheel problems, rotors, oil smells, AC going out, lights burning out constantly, etc. The service plan  I purchased ($3500.00) ended up not covering most of the things and when it did, I paid $200 deductible each and every time.
