If I have to rank them, here they are in order:

Performance -
Litronic headlights with low-beam rotation and self-leveling function
996 (5-Gauge) Instrument Cluster
Looking for a 997 short shifter

Aesthetics -
De-Ambered
Wood Steering Wheel, gear shift and e-brake handle
Painted bumperettes

Convenience -
Hard top
Glass window top and frame from an 04
Pioneer double-din navigation unit with blue tooth and iPod integration
Heated seats
8-way power seats with memory
Integrated Homelink garage door opener
Variable speed intermittent wipers

Some mods could fit in more than one category. For example, the litronics look better and improve performance.
