Although I don't live in Texas, I had a rotten experience with a dealership too.
I would not recommend the salesman I had to anyone. My husband and I went there to look at a yellow X, they did not have one but after many hours we agreed on a price, they said they could have us one in 2 days. They loaned us one for the weekend. When we went to pick ours up, there wasn't a window sticker on it. I asked the salesman about it and he shrugged it off, said he didn't know what happened to it. In the window was a paper that said "remove all stickers". I wrote to Nissan to inquire about it but haven't heard anything so far. Needless to say, I too gave him low marks on the survey we got from Nissan!!
