Like you've already mentioned, the differences are minor and the power levels should be nearly the same if the car has had the fix. I would advice you to at least try the seats in the 2001 before you decide, since they are generally considered more comfortable. The only other thing I can think of is with the 01 you get the 6 CD in-dash changer as opposed to a single player.
Either way, I doubt you'll be disappointed.
