After 11 years of constant fun it was time to upgrade. I've been waiting anxiously for the 2006 and I'm not disappointed. Much faster, much better ride, quieter, and just as solid. I love the new roof design, although I worry that the front panel will fade differently than the rest of the roof. But, since the roof is only up when it is raining, I doubt that it will ever show. We love the car so much, my wife is trading her Mercedes SLK 320 for another Miata (I can't bring myself to call it an MX5) as soon as she can find the color (Copper Red) that she wants.
New roof design. Greater power. Better wind and water seals. Great sound system.
The trunk opening is really small. I understand the trunk will be small, but the opening makes it effectively even smaller.
