SOLD CAR KNOWING OF REAR DIFFERENTIAL ISSUES AND NOT INFORMING SELLER purchased 06 chevy impala on 07/22 for 6500 cash.. advised the car was in great running condition. they fixed brakes which were scrubbing before purchase was final. The following morning i called informing of the awful noise coming from rear of car and they advised me to bring it back in on Monday and let them make sure brakes (which they ahd replaced at time of purchase) and catpillars were ok. On Monday 07/24 car was taken back in and ray - max and jose stated they would replace callipers and gave a loaner car to driver. we picked the car up on 07/26 and they stated they purchased a warranty since they did not hear the sound were were telling them about they didnt want us to have any issues with the running of the auto. we left and once again the noise started, which ray had told mr price if the noise happens again call us we want to make it right.we called the warranty after finding out the noise we are hearing is the rear differential (rear end) falling out of car. the warranty doesnt not cover this because it is an existing issue and the warranty is only been effective for 2 weeks and we will have to pay for the repairs. when i call and inform of the noise again like we had been instructed by ray i am told their hands are tied and there is nothing else they can do for us. after being told if the noise continues, call us and bring it back since wehn they had it to repair the callipers they didnt hear the noise, and here is warranty which is not worth a crap. when i called 08/07 and explained that the warranty would not cover this repair, jose states his hands are tied and that he mentioned to ray that i had called and that there is nothing else they can do for me. this place wants to show honesty and integrity, however 6500.00 cash and told car is in working condition? now i have a car sitting in the driveway thats paid for but not driveable? i am devastated at the lies of honesty they give a
