I test drove the 2006 MX-5 while my 1999 Miata was in for a regular service ... my mistake, I know, but I was so surprised about the improved handling (especially for windy roads!) and the new engine, that I decided to get the 2006 model. Nice handling, the manual transmission is very smooth, driving with top down is pure fun. It's like vacation for your soul!
Engine, transmission, improved handling, additional storage, competitive price, great design.
If there is any suggestion for improvement, when it would be to build-in a garage door opener.
