Most all options except park distance control. The panoramic roof was rare in 2004 but I have that too.
I have babied this car. It has only 82,000 miles on it works like a charm and looks cool too. Keeping it maintained and modern is so much more fun than mindlessly paying more money for a newer version.

I have those Eckler inserts for the front and rear lights, plus the chrome gizmos on the side. I replaced the factory rear lenses with the factory lenses from a 2010 SL63 AMG for a more modern look. I added a new windshield with MBZ original glass not too long ago.
