Normally I'd agree with you, but the 458 is so bloody good that even I felt happy slinging the back end around on roads that actually aren't that wide, and I'm far from a Lewis. Maybe you'd never get to feel just how quickly you could get round a corner in terms of ultimate pace as you don't want to be going that fast, but you can definitely feel the balance of the car and how above normal stuff it is if you're prepared to play with it. Whether you'd feel as happy flicking the 488 around as you may have to deal with a spikier throttle, I don't know.
Be interesting to see how you find the Cali T, I was far more taken with it than I thought I would be. Sure, the noise isn't 458 but then the Cali wasn't 430 as it's a different market, however it did make a better noise than I expected. Certainly had more than enough shove, although the steering is still a bit numb around the centre.
