.....I was looking at one they had in stock and at first noticed the seams around some of the fiberglass parts around the rear bumper had pulled apart. Upon looking further I found the top rear fiberglass cross member completely cracked through and the same on a side cross member. The sales guy seemed pretty honest and he didn’t know what happened to it. That did concern me a little because I could no see any direct impact marks, but it did look like it could have been collision damage. But it was odd that one crack was on the very top, one was on the right side, and the other was lower left around the bumper. I’m not sure what somebody would have run into that did all that, and yet didn’t leave an obvious mark that it hit something. That does worry me a little because it’s also possible it just broke in all those places when the driver hit a bump or something.
On the Viper, it appears that all those back wall protruding sections are installed after the rear wall is completed. If you removed them, you might have a generic looking back wall, of coarse without all the fixtures. My point is that none of them are structural, and any water getting inside through those seams and cracks, likely will not get directly into the interior. Still they should be repaired properly to protect the fixtures and "limited" water infiltration through drilled holes.
Here is a picture of the rear wall of a Viper.
