Excellent video... You could spend a life time researching and restoring these cars.
- I wonder what a car like that would be worth to GM?
Something of particular interest to me. The engine in that Corvette looks very similar to the original
186 cubic inch engine that powered many Australian built Holden-GM cars for decades. It was eventually enlarged to a
202 cubic inch. (They then used a Nissan engine for the "VL Commodore" onward's.

)
A 186 cubic inch "Red Engine".
