I am pretty sure that it is. I have attached their website. I have visited the museum before and it is very good. It is across the street from the plant. Look at the top of their web site and it indicates that they are only closed on holidays.
I have owned two Vettes. A new 1975 and a used 1977. I wish I still had the 1975 but they are antiques as compared to the new ones.
