Unfortunately, the Miata suffered from the same "bloat" as all other cars, and while it's easily one of the smallest production cars on the road today(or at least ones that you'll actually encounter-it's a rare site that I see a Lotus, for example) I'd still argue that it's gotten a bit too large and heavy for its own good. The current gen is nearing 6 feet wide and is pushing 2400lbs-again what I'd call large for a 2-seater.
It also doesn't matter what suspension tricks you use or how much power you throw at a car-weight is still CRITICAL in this class of car, and there's no way that you can really make up for it being too heavy.
We're not likely to see any non-exotic get back down to the 2000lb range, or at least not in the US, though. Safety and emissions systems weigh too much, and you need exotic materials to make up for that. The Morgan +4 is still there, as well as the Morgan Roadster, but again we can't get new ones here and likely won't ever be able to again.
