I had something sort of similar happen. In 2000 when I was in my mid 20's I decided to get my wife a new Volvo S80. We went to the closest dealership one night around 8 to look at one and take it for a test drive, they close at 9. I was driving a little Mazda B2300 at the time that had a recent dent int eh side that hadn't been repaired yet and we were much younger than their normal customers so it took about 10 or 15 minutes of the sales guys "discussing" amongst themselves who would get stuck with us before we got helped. They actually had the car we wanted and we talked them into a test drive but couldn't get any useful information out of the sales guy about the car, he clearly thought we were time wasters. I don't like being discounted like that so when we got back to the dealership, I thanked him for his time and we left without him even trying to give us a card.
This was the beginning of dealerships setting up Internet marketing/sales departments so since I now knew exactly what we wanted, I faxed every Volvo dealer within 2 hours of us telling them what we wanted and to send us their best price. We ended up getting the car at another dealer for $50 over invoice and did the whole deal via email except for signing the paperwork, I was in the dealership less than 30 minutes.
On the way home in the brand new car, we stopped at the other dealer and told the GM that we had just bought this car from their competitor because of the way we were treated by their sales staff. He wasn't very happy.
