 Bought with 50000 miles and worked fine for 2 years. Needed $1500 schedule B at atbout 75000k but that solved the acceleration problems. Had to fix the crank sensor at 76000k and no one really knew the problem cause. $250 for that one, then the engine light at 80000k was the air sensor- not a big deal but cant get car inspected with an engine light on. Air sensors are $500 from MB but got one from ebay, plopped it in and problems went away. Now at 104k and have had no issues..oh yeah, watch front springs they break at 90k. Replaced those as well. Power seats work when they want to and now fuel gage is not working all the time- problem comes and goes so unknown cause. Get trans fluid chged!
