My Classic Roadster came with the 17 digit vin, which Hawaii used.
My Kirkham has a 6 digit number which I think Texas used. I'll find out
Saturday. Must be because of the different areas but the Kirkham with a
declared value twice as high as the CR is 20% less on insurance - a nice
surprise for me. It stays in Texas - where I can at least drive it somewhere
other than circles!
