Old? Dah fk you mean old. Love my C6 (if) I ever get it back. (Oh the story got even better). 3rd short block finally built and hoping it gets on the engine dyno in a few weeks.
C6 is the corvette sweet spot IMO and you cant go wrong with a Z06. Make sure the heads have been fixed on older ones, I think pre- 2011. IMO one of the last analog vettes, best looking and very daily drivable, even modded. C7's are small inside where I have ample room in the C6.
Seriously, do all you can to avoid the old guys who value NOT driving their cars. I sh*t you not they brag about how many miles they don't have on them. Congratulations! You saved all the fun for the next owner.
I expect a major market correction for cars by 1st quarter of next year. Already some Porsche's are not selling on BAT and once the factories start cranking out cars again, including vettes, the prices will drop like a rock.
