Welcome Z0602, I am also partial to the C5's, & like the fact that the 04 is the last year for the hideaway headlights.....(Guess I'm old school) Hope you find the car you want....
Ron, interesting that you mentioned the pop up head lights. I like them as well, even when they are up.
Taking poor Z0602's thread off the beaten path a bit but here goes. We live in a fairly rural area, it is very dark here at night. I never liked driving at night because well the Mary Barra Motors C5 headlights just suck. I finally bought from Radio Flyer a set of bi xenon headlights. All I can say it is the best mod I have made to my car as yet. You can see very well but don't blind others coming towards you.
