I believe the computer stops the car from anything over 165. I don't think it has anything to do with the xmission type.
Saw from your other posts that you went and got an 04 - good for you! There's something to be said for having a "bird in the hand" - you never know what life will bring. Waiting for next years car is sort of like the people that were waiting for them to perfect color television... first it was color, then it was square tubes instead of round, then it was stereo, now its HD... If you wait you'll never get it, there's always something better down the lane.
