AutoNation review: fake autonation used car warranty

Purchased a used Mercedes from Mercedes Benz of South Bay, car was defective, dealer WOULD NOT repair the car under their warranty, had to return the car and lost my original vehicle. Do not purchase from AutoNation, their bumper to bumper dealer warranty is useless, they will not honor it. Had another AutoNation Dealer check the vehicle and they found bad front suspension and bad torque converter. They would not believe their own stores, they checked it at purchase dealer and confirmed car needed mayor repairs. This is a pre-owned certified vehicle with dealer warranty!
Based on this, have recently found many dissatisfied customers, also my loan officer from bank purchased a car from AutoNation and also had to return it due to "HIDDEN" transfer fee's that were over $1, 800. They are a scam company. U will be happy if nothing goes wrong with car, beware if you try to have any mayor repairs under "WARRANTY".
