.....UPS calls them "package cars". i had a brain fart...not "pie wagon". i used to work at UPS in the early 90's. they don't call them trucks. UPS doesn't allow it's employees to where any of there clothing outside of work. they are REALLY big on image. there trucks are washed EVERYDAY.
An acquaintence of mine has the contract for local UPS mechanical repairs. He says the old brown units are well built and have to be to put up with the abuse they get. However, he also says the Sprinters are the biggest POS they ever came up with. He claims they might be OK for someone who owns and drives his own, but these babies get really abused and don't hold up at all compared to the older units.
Don't confuse me with facts, my mind is already made up.
