Henry Brown Buick GMC

I'm extremely happy with my salesman. He helped me out tremendously. Where I have an issue with Henry Brown GMC is with the [non-permissible content removed] financial advisor. who added in charges on my vehicle that I don't think were necessary. When I looked at the build sheet, it already had tint on the on the windows and yet I got charged an extra $500 for that. Then I got charged an extra $1400+. for something else. that I have no idea what it is. It says it's on an addendum that I've never ever seen the addendum.
