Gang-I was almost certain that I knew the major differences, but now am questioning my own knowledge based on some used SC's I am seeing listed that perhaps are wrong in their ads.

I am looking at a 2004 SC and the ad says that it has adaptive lighting system and Bluetooth with voice recognition Nav. I thought that was for the 2005??? Also I thought that SC's (even my old 2002) had the auto leveling lights but not anything like the adaptive lighting like the LX and other high end Lexus cars have???

Was there anything done in the suspension or ML sound systems from 2004 to 2005?

Other than the engine/transmission/lights and colors, the 2006 is clearly the biggest year change for the SC, right?

For those of you who have the 2006+, is the manual shift really sporty or is it really lame like in most cars? My other car is an Infiniti FX with paddle shifters and rev-limiting match and it is like F1 racing! Fun, fun fun.

I did notice that the 2004 and 2005 SC won JD Powers initial and long term quality awards, which makes me wonder about all the issues I had that were rare with my 2002 that many people thought I was crazy about...maybe they had the 2004-2005!!!

Your help is greatly appreciated.
