Alderman's Chevrolet Buick GMC

Could have been an easy sale for Aldermans, but it was derailed at the last step over a few hundred dollars. After researching for 2 weeks, I found a used Chevy Volt I wanted to buy, at Aldermans. I'd looked at probably 40 cars online and 5-6 in person with test drives. I felt prepared, with a written list of 25 comparative cars in the region (within 500 miles). The car had been on the lot moer than 30 days and had multiple price drops. Seemed they'd be eager to sell. The sales rep Skye was very responsive, reliable, knowledgeable, and professional. She had the car out in the lot for me to see on sunday when the dealership was closed, so that I could decide whether to stay over night in a hotel to close the deal on Monday. We had driven 3 hours to get there from MA. She had the car ready and dried off from the rain when I arrived. After a positive test drive, we sat down and I started by saying I liked the car but also wanted a good deal, and had comparative prices to help with that. She explained the "Live Pricing" model, based on current market prices. We spent 2-3 hours discussing details of the car and the process including insurance and registration. Cutting to the chase, I wanted to buy the car and Skye presented the list price. I told her I knew where I wanted to come out on price. Rather than go back and forth, she asked me what that price was, and I signed an offer for that at $395 less than the asking price. She went to the Used Car manager and came back with his answer - No, the price is the price. I was surprised that he didn't offer anything since we were only 2% off his asking price, just $395. So I said my offer is my offer, I wouldn't go higher. Then he came by and told me again, he wouldn't budge. He'd done his pricing research and felt he could sell the car at his price. He'd just had a customer in the day before who passed on it. I told him about my comparative cars but he had no interest in any research other than his own. Honestly, I felt disappointed, but also disrespected and didn't want to do business with him or Alderman's at this point. I walked, over $395. I didn't want the car enough to give him any satisfaction, after we'd driven 3 hours, stayed over night, and worked with Skye for 3 hours. My wife also drove an extra hour north to retrieve plates from another car so that we could drive the car away that day, which would have saved Alderman's the cost of a driver to drive the car for us to MA. Not once, from my first phone call and emails to Skye, until the very end before I walked, did Alderman's tell me they would not negotiate at all on this car. The "Live pricing" is a great model, but it doesn't say anywhere they won't negotiate. If this was going to be their position, which it apparently was from the start, then the only fair thing to do would be to tell me up front. If they had told me this up front, that they would not negotiate at all, I would have had the opportunity to think about it before I did anything further, saving my wife and I an enormous waste of time and head aches.
