I have the same car except mine's Seal Grey with black interior. The only thing I don't like about the car now is that the wheels are 17s. Sitting beside my '06 Jetta with 18s and my wife's '12 Focus with 18s, the Boxster looks a little dated.
If only I could find someone who had 18s in that design that would trade for my 17s.
My mods: cupholderectomy, rear speakers, 9x7 short shifter, rain-sensing wiper controls, low temp thermostat, S oil cooler.
And don't forget, the '01s are best set up for replacing the 2.7 with a bigger engine!
