I never saw that video before. The owner has one incredible collection.
I am only 20 minutes into it and the video gets annoying because the guy shooting the video keeps asking over and over and over again, "What is this car doing here?" Or something like "Why hasn't the owner done anything with the car?" He is basically asking the guy showing him around, who is not the owner, what is the owners mindset or rational for keeping these cars in this condition. In my opinion after not getting a satisfactory answer after the first few times I would have stopped asking.
I got a little more into it and the guy shooting the video says he owns the Hemi Super Bee and and says it has been there for 15 years. He also says one of the Superbirds there is his as well as an AAR 'Cuda. So obviously this isn't what I would call a barn find since he has known about this collection for many years.
Everyone enjoys this hobby in their own way but if it were me and I was the guy making the video I would be wanting my AAR 'Cuda back and my Superbird so I can drive them and enjoy them.
