I don't care about the appearance of my truck. I inherited it once my dad bought a new car.
If I bought a new car, I'd give a shit, but I park under a giant oak tree every day, and every day I wake up, my truck is covered in bird shit. To clean it often enough to keep it in a decent looking condition would probably take about five hours out of every week, and I really just don't care enough.
Also, Cleveland winters are unforgiving. There's so much salt on the roads that rusting is just a general fact of life around here. Not much you can do about it, so why fret?
My truck looks like shit, but it's in proper working condition, and it serves its function. I'm happy with it.
