I love the new Z06, but to me having two cars with very different purposes works best.
I want my sports car to be light, agile, connected, manual, and alive - being the fastest thing on the planet isn't even desirable to me when it's just going to frustrate me and get me into trouble on twisty backroads. This is why I have a 1,950lbs Lotus Elise, which doesn't even have power steering.
With the single-purpose backroad carving taken care of, I want my daily to be comfortable, spacious, have the latest toys, be engaging to drive at any speed (read: manual), have a badass attitude while remaining subtly elegant, and be fast and loud enough to vanquish some of those pesky new EVs from the traffic lights. That's why I have a 5 BW on order. It's much like the E39 M5 I adored, but with everything dialed up a few notches.
While I'd love a Z06 and think it's an amazing accomplishment and value, unless I get a 3rd garage space (and more $$!) I don't think I'd want to replace either car with one. It's obviously not practical enough to daily with a young kid. And for the type of tight, twisty driving I enjoy, compared to the Lotus I don't know if something far bigger, 1,700lbs heavier, automatic, and frankly way too fast to truly stretch its legs and approach the limits of grip on the street would be any more fun.
