They are really great, fun little cars. I had one as a second car until recently (sold off) -- jinba ittai
The latest iteration is apparently even lighter and more peppy (Hammond was driving one with glee on Top Gear) -- expect a few folks to throw a "flyin' miata" blower on it and turn the car into a screamer.
Rear tails are ugly to my eye, but otherwise, I like the new design.
Still, not my preference for a next car -- it will be either a Z35 or a 4c.
