Was looking at Ford Diesel PU and came across this one.

I got the truck with the speedometer not working but it shouldn't have too many miles just by looking at the bottom of the truck/engine.
This line really gave me a chuckle.
All the years I have looked at vehicles, it never occurred to me to look at
the bottom of the engine to tell if she is higher or lower a mileage engine
when the Speedometer is inop.
