5 speed
I bought a 6s with a 5-speed. What a pain in the ass to locate a manual transmission with the V6, sport package, leather in Lapis blue.
The 5 speed is pretty good. I have been driving various manual transmissions over the last 10 years. The best manual transmission being in a 93 Nissan Sentra SE-R. The 6 is about an 8 on a scale of 1 to 10. The only thing I don't care for is the clutch engagement in 2nd gear. It seems to be a little unsmooth at slow speeds. Otherwise relatively short throws, no problems finding the gears. It's a very nice car.
