Product: Vehicle loan or lease

I bought a XXXX XXXX XXXX from XXXX XXXX in XX/XX/XXXX. It's the most horrible experience in my life and I just discovered more things about the car today!! 

To summarize, here are the 3 main points : 1. They will to rip you off if they find out you are desperate for a car.

2. They will offer you a deal and they will revoke it if they get someone else looking at the same car 3. They may sell you a demo car with 6000 miles as new and they don't tell you that until after you did the whole credit score and just before signing papers 4. The new car might have re-paint done without disclosing that to customer. That's what I found today unfortunately.

My old car gave up so I decided to buy a new one. I don't have credit history so I had to ask my grandmother to co_sign the loan. I tried a local dealership in kansas where I live and got good deals but my grandmum ( not very techy ) was not able to do the online process. She was not feeling comfortable with that So I decided to fly to new Jersey to visit them and get the car stuff done. First day we looked at XXXX XXXX and picked up a used XXXX XXXX XXXX. The next morning I called XXXX ( salesman ) and I told him I am willing to go with the XXXX XXXX if they sell it for certain price ( i think it was XXXX ). I told him to decide quickly with his manager so I know we do a deal or I go look somewhere else. He called me back and said, come on will do it. Because this guy already talked to us last day and he found out I'm coming all the way from kansas and I have to get the car thing done in new jersy before I fly back to KS ( my wife is driving it back ) he knew I am desperately looking to get this done especially with my grandmum ( the one that has the good credit ) lives in new jersy. I went there for the good deal and they started negotiating with me although that was not the agreement. He lied at me. I wasted all my time until then I found that another customer wanted that same car and they want to get rid of me ... Now its XXXX or Later and I don't have enough time to start looking over again and grab my grandmum all over the places for looking for better deals. I decided to go change plan with new XXXX XXXX  XXXX. It's a mess..They took at least 4 hours from the time we picked the car to the signing papers. We were so tired and wanting to go home that and they played us again..I negotiated the price with XXXX and he said he will drop it 1000 $ from what's priced online ... That took some of my anger..but then after going throughout the papers I found the car has XXXX  miles on it and it was a demo car which means the manager was using it..That 's a new car!!!. So he lied at me again. I was so desperate tired and want to move on, I was so.mad inside but I let it go..It is stupid that let it go but trust me when you are under that pressure, tired and don't want to bother your grandmother more than that, you will just let it go. Mr XXXX told me also that the warranty will exclude the XXXX  miles, which means, if the warranty if for up to XXXX  miles, for me it will be to XXXX  miles because the car has XXXX  miles already. Guess what, it  was a lie again. In fact, when I was singing papers with the financial guy he said that's not right ... one more thing, we ended up doing my grandmum as buyer and me a co-buyer to get a loan. But then in the title, they put only grandma 's name..that was a big mess that I had to fix later when registering the car in KS.Trust me you dont want to go through similar experience, especially when you find you paid XXXX $ on a car in someone else 's name. 
The boom finding was today..I took my car for a cash offer from XXXX and they found the rear panel and rear passenger door were re-painted. My car was more than a demo, whoever was driving it probably scratched it somehow and they had to painted. They did not tell anything about that. They said it's new ... 
I highly recommend not to go there.
