Also the gxp had an old 5 speed manual with really a really short 1st gear and a really tall 2nd, 3rd and 4th, so first gear would spin, hard to feel the power in1st and the other gears sapped some power because of the ratios. I just ran the numbers on the jb+ and its even more impressive.
The only thing that keeps me from getting the 35iS model is that it does not seem to hold its shift close to redline and just upshifts for you, which is understandable for an auto, but if they market this paddle shifting to be useful for the track, i'm having second thoughts, and am certain to get the 35i instead.
