Please learn from my mistakes, and do not trust your car salesman here. . Let me start by saying I love cars and I actually love car shopping. I went out to Shottenkirk Chevrolet to look at a new Bolt. I just wanted a test drive but I ended up making a mistake and purchasing a car. (never buy the deal, buy the car) The salesman was very nice they stayed late and worked hard to get us out in a hurry. I did fall for the negotiating by payment rather than by price, and I knew better, but that's on me. Just watch out for that. They also applied several rebates and did not inform me how much they were or if they were affecting my price, like a $3,000 Costco rebate for example. It was slipped in on the final paper but that never came up as we were closing the deal. I feel as though the salesman used it to earn himself an extra $3000. That was Wednesday at 9 PM. On Sunday and Monday I tried to get ahold of my salesman to tell him that this just wasn't the car for me. He did not reply. I sent a 2nd email with no reply on Tuesday. I called and was sent to voice mail. The next day, Wednesday, he did return an email to me. I explained that after 6 days I needed to return this car (I originally tried Sunday,Monday) he said sorry nothing he could do they have a 3 day 150-mile return policy. He did say they could buy it back, remember this is not even 7 days later, but that it would be a substantially low offer and a big loss for me. I was crushed, I felt I was ripped off so bad and overpaid obviously, and my salesman Cole, was your stereotypical car salesman, only out to make a buck, and must not care about word of mouth or repeat sales. . He did explain that the new incentives really lowered the price of the car (that I bought less than a week ago). I am not sure why he didn't tell me that night, that 1) I could return it in 3 days if unsatisfied, and 2) that new incentives were coming out in the next couple of days. My last car buying experience from Jaguar was so awesome, that I was over trusting this time. I feel he could have reached out and checked on me since it was a brand new experience driving all all-electric car, but he did not. He has not offered any ideas or solutions other than I do not want to sell it back t them because I will get a substantially low offer like $9000 less than a week ago. So Disappointed. I was trusting that my dealer would take care of me and put me in a good deal in a good car and make sure I was satisfied and that I would want to come back and buy another car. I understand they have to make money but I feel like he definitely raked me over the coals and took advantage of my trusting spirit Please learn from my mistakes and find a trusting dealer and salesman, maybe online is the way to go.
