I enjoy my Miata very much. I used to drive short distances to work and it was my primary car but since I do heavy interstate driving now I have purchased a larger car ... feel safer when trucks and SUV's are racing by. Love to drive it to the beach with the top down. Excellent quality, have never had any problems with it. Plan to keep it for many years. From an enjoyment, reliability point of view I rate it highly. My only concern was driving the Miata in heavy, fast-moving traffic from a "feeling safe" point of view. You don't get the respect that a larger car demands from other drivers on the highway when driving a smaller car.
Very easy to put the convertible top down. Fun car to drive. Reliability of the car is excellent.
