Appreciate all the feedback. Deal is done and being shipped next week. Taking with Shelby a month or so ago they did inform me they are 9 months behind on the wide body. The car also comes with the 800+ HP polished whipple. BTW the price was negotiated to what I thought was reasonable after doing the build through the Shelby website.
congrats on the purchase, honestly I'm surprised they would negotiate. I figured they would be pretty damned firm
