You say that like it's a bad thing! Sure, the Miata handles like a gokart. That's great!
BTW, the Camaro is NOT a sports car by any definition of the word. It's a muscle car (well, except for the V6 versions, which are just aerodynamic-looking slow cars). Nothing wrong with that, but by strict definition the Miata is the sports car, not the Camaro.
Also BTW, the Camaro has been discontinued. The Miata has not. Any guesses why?

Finally, the Miata will be running LONG after that Camaro has died and gone to the junkyard.
