Oil leak in E-550

puked oil, about 2 quarts, onto my driveway after 147 miles of being "fixed" by Mercedes of South Charlotte. So what am I to believe now/ Dealer says I need an oil pan. I purcheased the car at 47000 miles and it has never been right. What would you do next? Any advise would be greatly appreciated, is this a common issue, I am new to forum, this is my 3d benz, and the only one I have had issues with. Other than a small electrical issue with myold C240...
Is the car a CPO still under warranty? Have you checked the lemon laws in your state? More than x number of attempts (depending on your state's law) to fix a particular issue w/o success and you can lemon the car.
Have you tried having an Indy look at it for another opinion? How about another dealer?
It is not common for 07+ W211's to leak oil.
