It might be hard to get ahold of Liberty Mutual. When I moved to NJ from Boston three years ago, Liberty Mutual made it extremely difficult to get a quote from them. (Funny thing was that I was a Liberty Mutual customer from Massachusetts!)
The scenario would go like this: Call, put on hold for an hour, eventually get someone to take your address so that you can be mailed a form to fill out. Fill out form, mail back, and never heard from them. Call again. I'm told that they never received the form and that a new one would be sent. Fill out new form and did not hear from them again. (Meanwhile, my Massachusetts registration is about to expire.) I call again and am quoted X amount per year. The phone representative said that a policy would be mailed out.
I ended up buying a new car and decided not to wait for Liberty Mutual. It was a good thing as the policy never arrived.
When I called Liberty Mutual in Massachusetts to cancel my previous policy, the agent apologized and said they weren't sure why it was so hard to get coverage in NJ.
