Ive driven them a couple of times. The first time was back when the first one came out. I've always liked and admired the Miatas, but never loved them. To me, they drive like a very nimble and competent Japanese car. Nothing outrageous. Not brimming with personality. Because of the reliability and low maintenance cost probabilities of them, I had thought a time or two about getting one to replace my work Boxster for the long haul, but in the end, the seating is too cramped, and the cargo space is nearly non-existent, even for a sports car. I'd find an excuse to add one to the stable if it had that "gotta have it" factor.... but for me it just doesn't.
Doesn't stop it from being a very good car though.
