I'll admit I didn't watch much of the video as that car has zero appeal to me, but what I did see looks about like the Eagle moss cars, where you buy 3 or 4 kit packages that contain a few parts every month, and takes about 3 years to accumulate all the parts to finish at about a 15-16 hundred dollar cost, I sorta looked at the BTTF release when I first seen it, but for me that's too much money for what it is and having to keep track of all the parts and sub assemblies for 3 yrs till complete no thanks too much can happen in that time period, company goes away, lost parts etc, he is a quick read I found about the Eagle Moss cars
