I have a stick and a Tip. Love driving the stick, but the Tip is my daily because at 3,000 plus miles per month, half of it in gridlock city traffic, I'd likely have to have knee replacement surgery by now.
I've always liked the Miatas, great vehicles overall, but they're never going to win a beauty contest as far as I'm concerned. My real issue with them is an illogical one. They suffer from the typical Japanese Car Syndrome. Extremely capable, reliable, and innovative... but with little to no character.
I know that's an objective opinion, but that seems to be the (original) point of this thread. I wouldn't replace my Boxster with one, and that's why. As silly as it may be.
