I have zero clue on the total miles. It's got 85k on an overhaul without paperwork. New front rear end. New air compressor as of 2/23/20.
This truck was featured in the ending scene of the motion picture Bumblebee, so it is the legitimate Optimus Prime.
Ok, now here's what it needs: new driver's side door, some fenders, lower section of the grill.
The statement of the paintjob not being stellar also gave me a good chuckle. It seems truck fans and transformers toys fans have quite a bit in common.
You can find the listing here.
