Classic and Antique Car Insurance

i have American collectors.. been good to me so far but i haven't had to make any claims.
Well being with the same Ins Co since 2004 and if I can save $160/yr for the exact same coverage I guess this would be a no brainer for me to change in which I am planning on doing..I have done quite alot of research on American Collector Ins and I have heard a lot of positives....
