The truck looks pretty good. He has repainted it himself.
The price at the opening bid isn't out of line for a known good truck.
His emphasis that the mileage is 21,000 certified miles is full of crap. He has no idea what the real mileage is as the military changes odometers like most people change underwear. That bit of misdirection leads me to wonder what other details are being shaded...
Also, be aware that all of ebay ' s purchase protections and guarantees DO NOT apply to MVs. Even though their policy clearly states a title is required to sell any vehicles on ebay, they don't enforce this with the MVs. (Ask me how I know - a very expensive lesson for me).
Personally, I'd rather roll the dice on a gov auction than roll the dice on an ebay auction. But I'm a product of my experiences - I've had nothing but good experience with Gov auctions and one very very bad experience buying an M936 wrecker on ebay.
