Hmm. I wonder how much 6 mm will change the speeds and odometer. I do tend to be somewhat precise about such things, and I have been known to use the odometer to tell when to get gas. Extensively.

That does leave the question of how to tell this guy to get lost (or at least that his prices are crazy high...)

OTOH, supporting local businesses is (almost) always a good thing.

I am the Doctor, and THIS... is my SPOON!
