Re: '53 Cruising Speed

All GPS models should be extremely accurate measuring speed (not as good at measuring exact location) but for speed they are all great. That being said, I personally have had great luck with all of the Garmin models. Their customer support was good the one time I needed it. The reason my speedo is not accurate is that the modern radials are smaller than the original bias ply 7.6 X 15's. My speed was within a 1-2 miles an hour when I had the old tires on it.
