mercedes Benz of Calabasas

BUYER BEWARE!!!!!
We just bought a Subaru Legacy GT Limited on January 11thWe were promised that the car was in sound mechanical conditionAs they stated, their mechanics were looking it over and checking everything while we were going over pricing and termsHowever, on January 14th, as my husband drove home from work, thick black smoke started pouring out and the car slowed down to mph and wouldn't go any fasterHe barely made it home, and immediately called the salesman at Mercedes Benz of Calabasas to let him knowIt took several phone calls to get a hold of him and the managerReminding us that we signed an "As is" note, they agreed to tow the car backWe were hoping it was simply a minor problemThey towed the car back on January 16th, but just got back to us tonight, January 19th, to say that we needed to pay $to get a new engineThey might contribute $of thatWhat?!?!?!?! Our new purchase only worked for 2-1/days and there is nothing else they can do? That's not what the "As is" agreement is for!!!! They should be more willing to work this out and take the return of this carThey misrepresented the condition of this car in the saleWe were very impressed with our salesman, Antonio, and hope that he had nothing to do with this scamWe are very disappointed that Angel, the sales manager, and Thomas, the used car manager, are not willing to make this right
