Supply and Demand...
The Supply-Canadians can no longer buy newer pre-owned Corvettes in the US at a reasonable price due to the exchange rate this keep the Canadian supply at a minimum for example a US bought 2019 Grand Sport 2LT coupe with under 10,000 kms would cost about $87000 CDN +HST after importing so it makes sense the average person will pay the same here for a Canadian car without the hassle of buying and import from the US
The Demand-Buyers can't just walk into a dealership to purchase a new Corvette off the lot they have the money burning a hole in their pocket and they'll opt to purchase "like new" low kilometre 2018-19s then it's a snowball effect down to earlier model C7s and even later model C6s which have risen substantially in price also we've had multiple clients who were on the reservation list for C8s that didn't want to wait any longer buy C7s
