We do the same thing or vise-versa. The last car we bought was used from a major dealership. We looked at the car and tried it out. When we were negotiating the deal the sales guy we were talking to flat out lied to us. It was over a very minor thing but we walked away. We came home and talked about it a couple days. It was a very good deal, so we called the dealership back and ask to speak to a sales person other than the one we had talked to a couple days prier. We then talked to a very nice saleslady and made the sale over the phone. We even got a better deal than the guy was giving us.
We had the car almost two years and every year they call on my husband's birthday and have been very good to deal with. We will be looking for a pickup in a few months and will go back to that dealer.
