Wear of paint is not a good one to judge by as many if not all military vehicles are stored outside for years and the paint can look really bad on a vehicle with only a few thousand miles. There truly are a lot of mil vehicles out there with VERY low miles. Yes, they change speed/odos in them when they break but the sheer number of low mile units can not be written of to guage changes. Look over the vehicle closely, pedal pads, underside, engine bay as these will give away the truth about if the odo is acurate or not. I have an M1031 with under 7K and it wasn't hard to prove that out with a thorough inspection.
