"My question was also about how this will affect the value and if anything from that time period will be remembered like cars are."
I don't know ..
" I'm guessing that '71 would have been roughly the same price as '72. "
Guessing the 1971 CV21 would be a few hundred less.
I check CL / eBay / Kiji / Marketplace every other day, I see asking price but don't know the actual selling price.
Asking price's are increasing, some are twice the amount of two years ago.
There was a CVX16 with asking price of $10,000 that sold about two weeks ago.
Saw a beautiful CVX16 at the meet that owner got about a month ago for about $3000 ..
New Glastron prices start at $35,000, Covid has boat / RV and other stuff selling like crazy .. I been told.
Most CV21 that come up for sale are in ruff shape.
