I have an 06 Roadster with the 6MT. I'm in my 60's and am a fairly "sedate" driver. But I have noticed that there seems to be, at least on my car, a definite sweet spot in the first 3 or 4 gears. If I shift between 3500-4000RPM then the shifts from start up through 4th gear are pretty smooth. If I shift at lower engine speeds, like 2500 then it isn't as smooth and you can almost feel more meshing effort inside the trans. My prior car was a Mini Cooper S and it felt the same. Maybe it's me? Also, I think there have been other comments here that the first 3 gears are low and close together so you run out of revs in a hurry.

Anybody else notice that engine speed makes a difference?
