By any chance... did he step into another dimension?
Seriously, imagine all the great conversations and bragging rights you could get with 546,000 miles on the Odometer...
"Oil change? Are you supposed to do that?
It reminds me somewhat of my 1979 MGB, that I rarely use for obvious reasons. Guaranteed, every time I take it out for a spin; something breaks. Last time it was the speedometer, which went "Vrzz, vrizzzz, zzork, wizz...clunk", and died. I put it back in the shed, pulled out the ignition key, shut the door, and haven't cared about it since. Quite possibly the worst car ever made? Well, at least a runner up, or "Top Ten".
Ride Safe (and hopefully within THIS dimension)!
