You do realize that the majority ownership of these cars are NOT "enthusiasts". They liked the car. They bought it. They drive it. ( maybe not like you want them too) 😂
From what I've read across multiple car sites, is that "we" are less than 10% of ownership. Corvette since the C5 have been producing north of 35-40k units a year. I've encountered many people in a variety of cars in the past 20 years(internet era) and most have never heard of any of these forums and have no plans to modify, race or display car at a show.
I'm with you tho, it saddens me to see these cars not driven to thier potential, and maybe they are, were just not seeing it. 😣
