My fiance and I were car shopping and this was by far the shadiest dealer we encountered. They had a VW we had our eye on, but when we ran the NADA numbers on it, we found out that they had it priced $4000 over what it was actually worth. They wouldn't negotiate the car down to where we felt we weren't being cheated.
On top of that, I felt like they were often talking down to me since I'm a female. Even though I definitely don't know much about cars, treat me as your equal!
