Worst experience ever tonight. Bait and switch tactics. I have AAA. I'm thinking I'm going to use their free car broker service. I'm so angry at the bait and switch tactics that happened at Courtesy Chevrolet. I was dealing with Oscar on Saturday who I supposedly had an appointment with today, but when I got to my scheduled appointment, he had left for the day, so another guy was assigned to help me, Ryan. This guy instead of starting off where I'd left off with everything Saturday, started the whole process from scratch, and even went back to saying he could get me a new car after I told him I already tried that and it wouldn't get approved and that anyway, I had always been interested in a pre-owned car. I even told him which car I was interested in. He took all my information again and ran my credit, again. They should have had a file started on me with all my information from Saturday. I told him what I was able to put down but as a deferred down which is what I'd agreed to on Sat. After waiting about an hour and a half, he comes back and tells me he can't sell me any car new or pre-owned unless I agree to $2500 down. I tell him, "no way! That's never going to happen! I'm just going to walk away." I get up. He then says they have other banks that would approve me, but the finance guy who deals with that financing went home at 5 because he only works during banking hours. I tell him that I'm mad because he's giving me a completely different story from the one Oscar did on Saturday and way worse numbers, a much worse deal, and I feel mislead. He gets defensive and says he'd never lie. I say that might be true and maybe the other Oscar made a mistake with me on Sat when he scheduled my appointment for after 5, and that I was lead to believe that the only thing I needed today was my pay stub, and then we'd finalize the financing we started Saturday, test drive cars I qualified for and do final negotiations and I'd have a car tonight or tomorrow night at the latest. I told him I don't like what happened and that I was tired, had worked all day, and was leaving. He said fine, didn't offer to get the sales manager, or try to set up an appointment for Saturday with my original salesperson, Oscar, or somebody in pre-owned since according to him, "I'm a new car salesman." He seemed like he didn't want to sell me a car at all unless I could get him a certain type of commission frankly. The guy I was working with Saturday was also a "new car guy," but he wanted to sell me a car. He was fine showing me pre-owned and was worried I wouldn't come back when I left on Saturday. Now this dealership completely lost my business because of how this guy handled everything tonight and because I felt like they were using bait and switch tactics on me, and didn't seem to care about getting my business or the bad word of mouth that's the result of how poor my experience was overall.
