I didn't know you could buy a car through Costco. I think that's great.
For DR Laura, I will tell one of my car-buying stories:
Many years ago, when I was living in San Diego county, I needed a new car and wanted a new Honda Prelude. Expecting the dreaded high pressure, I asked my friend Mal to accompany me. Now, Mal is no fool; he's a pretty tough cookie. I thought he'd help me negotiate a good deal. I had overlooked the fact that he is a COMPULSIVE reader. As the salesman and I haggled, Mal was TOTALLY engrossed in a magazine--not a peep from him. I kept looking over at him, thinking, "Aren't you going to say something?" No. As it turned out, I did get a good deal. My first choice of color was grey, but they would have to order one. They had a blue one--my second choice--on the lot and equipped as I wanted. By compromising on color I was able to get the price down considerably. Moral: you get the best deals on the cars on the lot.
Good luck to you, Laura!
