As an owner of a "Sport" Auto Pro5 I am going to give you the same advice as most everyone else here. Unless you have a hideous commute go 5 Speed all the way.
I commute 35 miles each way every day in some of the worst traffic in the country, that's why I went with the sport auto, but I never expected this car would be as much fun to drive as it is, if I had it to do over again, I would strongly consider getting the manual and my next car (probably a 6 down the line) will in all likelyhood be a manual. I drove a 6s this past weekend with the 5 speed and oh do I ever wish I had one.
