You didn't build this model. It's a promo given to potential customers by a dealership. You proved it by showing the chassis, it has the stampings of the car's features on the bottom. You ought to be ashamed for claiming this is a kit build.
Did you see the work in progress video that I released exactly 48 hours before this video came out? How about the unboxing video that I released on August 3rd of last year? I believe AMT did have this as a promo back in the day that they eventually turned into a curbside kit.
