I had been thinking of trading my vehicle in for a different one. I went to one dealership that said the only reason I couldn't get into the vehicle I wanted was because of the high miles on the used vehicle I was looking at. My vehicle is less than a year old so I understand. I saw an advertisement for this company that said they were paying off all trades no matter what is owed and no money down. I had someone contact me and before driving over a half hour to get there, I asked all the right questions. Does the pay off actually mean pay off or is it rolling over whatever extra is owed? Is there a true no money down option? I have never had to put money down so I wasn't about to start. I was told definitely pay off the trade in full and no money down on vehicles, including rebate options on new vehicles to get me in with no problems. I get there and Casey tells me my original sales person is on the phone. He quickly smiles and introduces himself. When he sees my boyfriend, he assumes he is another customer (don't assume based on race). His attitude quickly changes. Then I am rushed into the application process where the insults begin. I must be in there with no trade or something worth nothing and low income. I inform him I drive a 2018 currently and my income is several thousand a month to which his mouth visibly drops and he says oh ok. I proceed to tell him of the conversation I had with the other sales associate and he immediately says no. They aren't going to pay off my trade in full, the difference will be rolled over. Then he says I probably need money down or a cosigner. I haven't had a cosigner so why do it now? He then takes my vehicle saying his boss is going to look at it. He was gone only a couple minutes. When he comes back, he brings a piece of paper showing what a 2019 is selling for. I told him I know and don't care because i know how much mine is worth (which is almost the same) and how much mine is selling used for. He walks away and comes back a few minutes later claiming my credit score has dropped nearly 150pts in 48 hours. Then tells me I won't be approved anywhere. I told him my current company will finance me, to which he says we don't use them. I was there less than an hour which is less than I have ever been at a dealership, buying or just looking. I then get home and my vehicle has damage to it that was not there prior. This vehicle was cleaned only a short time before and the damage was not there. Probably why we were rushed out with no sale. I will go back to the dealership that doesn't lie to get me in and really will get me in a new vehicle no matter what. Oh and there was no care that I had gotten off a 12 hour overnight shift before my drive there.
