I absolutely adore my MX-5. It's a series one bright yellow California with the pop up headlights and it is a wonderful drive. Insurance has come down since it has become such a popular model and it is inexpensive to maintain if you can find a dealer who is also an MX-5 fan. I go to Paul Sheard who has an MX-5 racing team and maintains all his own cars. His prices are very reasonable. I bought the car form him too four years ago.
Go for it and have a lot of fun on the open road.
