Can't speak for the states, but here in Minnesota, motorists pay
an annual auto license registration fee, the amount of which is
pegged to the residual value of the vehicle. Minnesota used to have
one of the highest auto license fees in the US, until Jesse Ventura
passed a law when he was governor to reduce the fee to $100/year
when the vehicle is three or more years old.
Other than that, I can think of any other fees we pay on our
vehicles. But motorists here are getting slaughtered by high gas
prices, though.
