"The median age of a Corvette owner has risen from 54 to 61 during the past 10 years...." See link below for source & more details.
This seems to indicate that the people buying Corvettes in their 20s thirty years ago are the same people buying in their 40s ten years ago and buying now in their 50s. But, they're not being replaced by younger buyers. If that demographic trend continues, eventually there will be no more Corvette buyers left to support building the car. Harley-Davidson has the same issue.
