1999 Mazda Miata
What could possibly be more fun than a Mazda Miata? OK, you could say a BMW Z3, Mercedes-Benz SLK, or Porsche Boxster. But when you say that, the discussion gets to be a lot more expensive--$10,000 or so more.
So here's a better answer to the question: a redesigned Miata. It's lighter, more powerful, more refined and boasts a stiffer chassis than the previous model. And it is still the only true sports car that can be called affordable. Sounds like fun to us.
