I never saw a build sheet? I have a tendency to stay away from dealers. I agree with the statement above you need to go or have someone go look at it for you. Never spend the kind of money you are talking about with out taking a few hundred dollar trip out ot see the car. Also welcome to the site.
This is a friends car here and It is a very nice car. It would go for about the same price.
