Business ProfileforGrand Slam Auto Sales

I purchased the vehicle from Grand Slam Auto Sales on 02/17/2023. I test drove the vehicle and asked about the rubbing sound/feeling and was told it was probably the brakes because the car had sat on the lot for awhile. The rubbing sound never went away. The car smelled like burning rubber within a week of driving and after a couple of weeks it began to smoke. I was told to bring it to have it looked at because it was "probably just a gasket and not a big deal". I dropped of the car and their mechanic did the repairs. Almost immediately the vehicle ran rough, when the acceleration pedal was pushed and released the car would jerk as if the engine or transmission might fall out. It was brought to the sales persons attention and I was told I may be able to purchase a warranty..several days go by and I have heard no reply. Today, 04/01/23 I started the car to find a loud exhaust, it had been broken at the weld due to a broken motor mount which explains the engine jerk that occured after being worked on by Grand Slam Auto Sales. I read the reviews after the fact and found that other customers have also had issues. I stressed that I need a reliable vehicle because I drive a good distance for work and have an autistic child but I was sold a vehicle that had far more issues than they disclosed (which was none). How to I pay for a vehicle that I cannot drive?
