Yeah, the sun does beat on the paint down here for sure. My 99 Silverado has started to get clearcoat failure and when I bought it from the original owner in 2008, he garaged it.
The other thing is that a lot of trucks this generation have been used as trucks (some work trucks) so they are really beat up, and most are going to be almost 200k, if not over.
But there are good survivors, mostly owned by older folks that take care of theirs vehicles and are just grocery shoppers and driven to Sunday church.
I saw this rare 2 tone recently and it had around 150k and I want to say it was like $4500. Great deal, in my opinion. I'm sure it's gone by now.
