I can't imagine Google being 100 miles off for the 1000 mile trip I make to see my family in Myrtle Beach.
Maybe I was not clear (not the first time!). ...It's more like, hypothetically, I drive a distance & my odo measures it as 81.5 miles, Google says it was 85.6, and the GPS says 85.55...

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
