My roomate bought a used car from a private dealership on july 11, 2013. We were told that the gears were slipping but if she took care of it, it would last forever. 20 days of owning the car, she had to pay 100 to get the axel boots fixed and on Aug 2nd the transmission blew up. The dealer is refusing to let us compromise even though we have had the car for twenty days! What can we do??
