 Never buy a Mercedes. They are not reliable mechanically. The SUV spent more time in the shop than on the road. Diesels are not the way to go because you will have to replace the DPF filter at a cost of 4500 to 6500 dollars. Short trips the kill the DPF filter faster. That is almost half the value of the SUV. Mercedes should be sued for allowing this piece of junk on the road. I will never own another Mercedes again. The diesel engine which you can Google and read about is junk. The engine is an OM642. The engine oil is 10 dollars a quart and it drinks it at a rate of 1 quart every 1500 miles. Do the math on that one. The urea tank heater will fail which is 1500 dollars. I think it is also a bad great idea to not have a spare tire either and no place to put one.
