All that Canadian stuff, unfortunately, is all wrong. My car has a metric speedo, but the numbers are the same retoro type numbers.
As far as milage reports are concerned, it all has to be legit. In fact a used car dealer here in Toronto was fined a couple of months ago $ 50,000.00 and lost his licence for odometer fraud.
My guess is this guy wants to sell in the U.S. because of the dollar exchange $ 1.60 CDN for $ 1.00 U.S. ( it sucks, I know )so to convert the cluster to MPH he just grabbed anyone that would fit.
