CarHop Auto Sales & Finance review: Used car

So I went to CarHop in Des Moines Iowa February 17th to purchase a car I paid $400 down and I drove away with a car that was not a good goodbye so I got a Chevy Sonic LT and after purchasing it the very next day mind you I'm on oxygen because I'm awaiting a lung transplant as well as telling my sales rep Austin that I was waiting on transplant in this car was needed for me to get back and forth to my medical appointment and something that was fuel economy I'm paying a car payment of over $400 a month and I didn't I haven't had air since the very next day that I bought the vehicle and they said they they told me they verbally told me they were going to fix it no problem no problem and when the issue came up where I wanted it fixed they they don't cover that under warranty so here I go I can't breathe in this heat and it's been over a hundred degrees in Iowa this summer I have missed my lung transplant appointment so I've gotten kicked off the list so this will actually probably take my life because so I got I was told I need a new engine at my first appointment one week six days after I had the car then I picked it up and it didn't have any air conditioning still in it still was like moving around quite a bit so I took it back and they said the motor mounts were bad or they didn't put them in or they were missing or something I'm not sure exactly and then I had to take it back in because my thermostat housing was leaking and when I took it in they said well that's not a drive that's not a driveability concern so we don't cover that either and then I had to take it back in for my brakes to be fixed because they were grinding metal on metal and they told me Christy the the manager of the place told me you drove 3000 Miles that's going to happen with a used car but today they were warped the rotors needed replaced like I am put so much money into it already like and I live on social security disability my house is going into foreclosure because I have to have a car for my medical appointments they took advantage of me totally in shame on them people for that and they will have to meet their make her one day and when they do good luck.
