I've said this before on these "what do you pay" insurance threads. You can not directly compare your rates to someone else's, there are too many variables. What you can do is shop around when it is to renew, at the very least.
Variables include population density where you "garage" the vehicle, your personal driving record, state and local statutes, not to mention the coverage you are quoted/asked for. (Rarely does anyone on these threads list all the exact coverage and limits they bought)
