The doors on C5 I think are sagging. they may like a thump when I close them. What can I do to fix this

Check the hinges for wear. I admit I haven't looked closely at mine, less then 8k on the car. Other cars I've owned in the past need the hinge pin and bushings replaced. Solved the saggy door problem.

Sometimes the window angle adjuster works loose and makes a noise when you close the door or hit a good sized bump. Easy to check, just remove the red reflector on the inside door panel, there is a nut there, see if it's loose.
