707 Hell Cat, what does it mean?

So, have the early Muscle cars become the flathead ford?

No.

These past couple of generations of Vettes are hands down superior in ride, handling, power, amenities to the first few generations, yet guys are still doing high dollar builds and spending high dollar amounts for what came before for about the same money as it take to buy a new one (or more).

For the most part the Hellcat won't affect those of us building on a budget. It won't affect the prices of high dollar cars swapping hands. Guys like Tim Wellborn will still be dropping large amounts of money on his collection. And guys building on a budget are doing so for a reason.
