Hmmm, I wonder if yours has been apart a lot. I’ve always been amazingly impressed by the engineering and packaging with the C5 as I work on it. And the build quality has always been at least suitable in my opinion. The paint is “meh” at best (amazing color but orange peel like a mofo, shows up least on my color but black looks shit), body panel gaps are pretty odd (look at the gaps around the hood on any C5, it’s never even close around the headlights, down the length of the fenders etc), but everything is at least put together pretty solidly and for what it is the car is pretty reliable.
