I got a 2001 CL-S with 43k miles...
I have the DVD Navigation, upgraded to the version 2.05 (2003)
it is mostly stock - some mods:
-shaved trunk 'A C U R A' letters
-removed front license plate

soon to come (hopefully):
-lowering springs
-35% tint
-silver decal to cover amber turn signals
wishlist (way future):
-OBX ceramic headers (add 30-35 hp)
-19" wheels (either C5's or diablo viennas)
