 I bought this card 1 year and 3 month ago for 9300. dollars.  took it to the dealer for check-up, they did not find much wrong with it except for about 1100.00 dollars worth of work. I did the repairs to put it  in tip-top shape.  Thinking Mercedes has the reputation to last. The car was running well, looks in perfect condition and was running well, 86,000 miles when I bought it. I expect to have repairs with a used car, but not powertrain problem with a Mercedes at 92,000 miles and computer issues. The car has a lot of computer issues that controls everything. The transmission would not upshift pass third gear and the check engine light comes on and the rpm revs up, but it would not pass 35 miles. My mechanic said the computer card that controls the transmission needs to be replaced, it cost 1800.00 to fix. I have seen a lot of reviews with other people having the same problem and Mercedes won't fix it. As a matter of fact, lots of people appear to have problem with the engine also which cost even more. My last Ford explorer had 140,000 miles and no problem with the engine or the transmission. My advice , Buy American Cars. Mercedes is not what it used to be. There is only a reputation left.
