The current-gen mail vehicle is called the LLV - literally the Grumman Long Life Vehicle - and the mileage these things have taken on speaks well to the name.
USPS tends to order these things with the expectation that they'll last forever (400k+ miles) with relatively little upkeep. Most cars out today, even if they get to e.g. 200k miles, will probably have taken on some pretty major repairs.
