That's it, feeling.

The same way a Mazda Miata gave you the feeling of driving a british roadster of the 60's while having much more modern internals,comfort, reliability and fuel economy.

I've never felt comfort in a Miata haha

Interesting final point you bring up because all of those shortcomings are part of the experience, without them you’re experiencing something completely different. (As a classic car owner that’s not entirely a bad thing in the case of the MX-5).
