Well I can tell you for a fact that in PA the H1 is considered a truck and not a car like the H2. I went from paying $35 for registraion on the h2 to something like $190 for the H1 (might be some extra dealer cost in that number but it's still a good deal more). Based on weight class...
Small price to pay though. Love the H1.
