They would have to be anticipating sales like the C8, and there would be very few LT1s to be found today. Almost everything that were seeing is the LT2/3 range on or about 85-120k. Chevy can do this and lose money on the Vette, because the rest of their lineup eats the cost, they know Vette owners are a small margin of profit, and that's a hugely small market. If they're going after that market I think they'll find that the Corvette market is a cult, and they're behind the power curve to compete directly.
They are well suited however to go after the Mazda Miata, but that's a different topic entirely I imagine.
Or they do like Alfa introduce it, as the 4c was, then pull the plug counting on introducing a Sport Saloons, and SUVs to take the brunt of the ROI.
Noone is going to ask me, but its exciting, I personally think they'd be better off making the safety modifications to their current Elise/Exige Lineups as a reintroduction to the US, heck pick an Elise any Elise, almost any condition and its 30k if its road legal. After which pushing the new platform.
Curious stuff really, and pretty exciting.
