I'm pretty cautious when it comes to a purchase as big as a car. I asked a ton of questions, I came back several times, and all I was ever met with was patience and understanding.
Everyone I worked with was friendly and helpful. These guys really do believe in the slogan they have on a number of items "we'll do whatever it takes". They really aren't kidding about that. They will, and they do.
I purchased through the Costco program, so the deal was perhaps more sanitary than if I'd come in on my own, but I wouldn't hesitate to send anyone in to see them.
