 This is the 4th new Miata that I've owned.  I've had at least one of all 3 body styles.  This one is great, but the trunk opening almost made me keep my 1999.  It's just too small.   And the lack of a spare tire WAS a problem for me when I had a blowout at 9pm at night and the flat fix kit didn't work.  AAA towed me to a motel and then came back to get me the next morning and towed me to the Mazda dealer (the only place that said they had a tire that fit).  Fortunately, they were able to repair the tire.  Overall the additional power of the 2006 and the new features were the deciding factors for me.
