Business ProfileforSherman Chrysler Dodge Jeep Ram

I went to a car lot with a guarantee to purchase a car from the dealership. I submitted a pre approval application. Immediately a finance manager called me and setup a time to come in. I explained to him what was on my credit, and how I was in a chapter 7 that was to be discharged soon. He expressed that I would be fine that they go off my income not credit. I was hesitant because I live in the city on the east side and to travel to Skokie its over a hour drive and plus my Uber or gas expense. He rest assured me again that I would be fine trust him and he gave me a 500 dollar credit towards my vehicle choice. We scheduled my appointment for 2 weeks out. During that in between time we have communicated my interest of still coming in and also my ch 7 was discharged, I was told most definitely youre going to be approved and that would be my last Uber ride. I get there and I was never greeted by the person who I was speaking with and I was told he will be the person Ill see when I sign my paperwork. I gave my check stubs my discharge letter and ID. I got in there by 1:51 and then by 2:30 I was told to pick 3 vehicles I did so and then I was told they have to run those numbers with the bank. When I gave the person who told me to pick 3 cars I saw him put my paper in a black bin at the end of the counter. I called him over and asked why did he placed the paper I just gave him in the bin and he said its a process for the finance department to grab it and Im the first person. However the same person grab the paper and he sat down at a desk. 30mins or so later he ask me to move to another desk. He showed me a screen and basically said I need a co-signer. I was not told this would be an option. I wasted time because its now 4:30, and I wasted money to get there. I just discharged my ch7 and now I have several hard inquiries from this dealership. They have false advertising and are causing more harm to people credit.
