i test drove a really nice red S4 today, first time ever driving one... i love red cars and was quite surprized that when i started her up all of the interior lighing was red too! are all of the b5 S4's like this? with the red interior lighting?

 

not all the interior lights are red... if you are referring to the map/dome lights... there are two red lights that are up on the sunroof control that shines down on the gear shift area... if you are referring to the dash lights, speedo, odometer, stock stereo, then yes they are all red...
