Auto vs manual was the only decision I wrestled with when I placed my order. I test drove both trying to get a feel for each.
I finally settled on auto because A) it's more practical in the city where most of my driving occurs and B) it's more practical with all of modern life's distractions (cell phones, mp3 players, kids, etc).
And when I found out the 2SS came with paddle shifters my mind was made up!
