I used Midwest Classic Insurance (
http://www.midwestclassicins.com/) and they did a 3K policy for me without any other vehicles needing to be moved over. It cost me the huge sum of 220 dollars for the year. If I move up to the 6K a year (not likely) I am sure it will be more, maybe even double, but they do stated value policies if your state allows it, and thats huge.
