My 02.
Regardless of the C7 or C8 question, the draw for many to the Corvette lineup was affordability. It was always within the grasp, financially speaking, of the common middle class working guy. The European exotics were not. Even a 3 trim Z06 C7 was likely affordable if a guy put his financial house in order. Even easier to get into a GS or a Stingray. Of course the MacDaddy was the ZR1 but in driving a Stingray or GS you were at least in the family. Then along came the C8 and affordability has left the building. First find a dealer, pay well over MSRP, and you can find yourself at $150k without blinking. Most assuredly tickling the $200k mark for a Z06 and only Allah knows what a Zora will cost. Affordability is toast. Now to make matters worst, the supply chain, the Covid, and the C8, have dragged used C6 and C7 prices into factory new MSRP numbers for the model years, and we have kicked affordability out of the used market as well.
So get to the point Al....The point is that Corvette was always the working man's (sorry ladies) sports car. That was a massive demographic with guys saving their beer money up for a Vette down payment with a retail price tag that may have made mother crinkle her eyebrow but in most cases the frying pan did not get a flying lesson at your expense. The C8 has changed that. If I need to spend $200k, and assuming I can, I can go get a mid teens Maclaren 650 GTS, or a very late teens 360 Spyder, stuff that will really turn a head a two. Cars that will retain value into the distant future. My position is that yes the C8 is a cool car but the economics (I am not even convinced this is what GM was aiming for) has moved the Corvette into a different market niche. A smaller one with likely more discerning buyers, but certainly not the Joe Six Pack crowd.
So to the question of trade. Nope. Why? Because the C7 and C8 crowds are different. Different tastes, different appetites, and likely different economic demographics (generalization). I am a front engine muscle car guy and if I was to win the lottery I would go get a Mclaren 650/750 or above. So there will be little unity on the question as asked because the question is do you really want the steak or the seafood.
