At the end of the day, these are still 40 year old cars. I'm not sure you could ever get them to the level of compliance you crave on the refined side.
I'm with you on the middle ground and days where I would prefer a full blown race car. I'm at the point where I don't care to street drive mine much. I put plenty of miles under my belt during the week. I don't come home and think, man I'd like to go for a drive.

Then again, I do think I'd miss the street aspect. Those lazy cruises down the interstate, driving to the track, kicking ass, and driving back home. There is a certain amount of pride there as well.
I'll take you up on that test drive.
