After 12 years of MT, I've come to enjoy the Freedom of the AT.
But nothing beats the MZ5 with a teenager in the family who just got a license. I don't have to do the driving anymore. Mazda5 now comes with
a willing driver. I hope the enthusiasm lasts longer.
I was a lifelong MT driver for the first 18 years of my driving life. I switched to AT a few years ago. I must say that I now prefer the AT about 90% of the time. Yes, there are times a MT is great (esp in inclement weather) but I would have to say that much of my enthusiasm for MT was sort of a man-pride thing. It was simply "cooler" to tell people I drove a MT.

Of course if you are into racing a MT will be handy but no one in their right mind will mistake a Mazda5 for a race car. It's probably their slowest vehicle they sell (minus the Tribuite). Probably that is why they only sell it in the Sport version.
... maybe the biggest thing I miss about a MT is not having to press the brake at a stop light.
