Being in the business for a very long time, I have found that most people are clueless about insurance, even most agents who sell them. I will agree that their rates are cheap. But I wouldn’t recommend them. Inexperienced adjusters. They do not fully investigate. The policy does not cover like, kind, and quality which is bad if you have a new vehicle.
To transfer your insurance from one car to another you will need to contact your insurer in the first instance to advise them as to your new vehicle details. Your insure will then recalculate your price and offer you the option to either insurer your new vehicle or cancel your policy. You will have to pay either a mid-term-adjustment or cancellation fee to cover the administration involved in changing your insured car.
I was with Liberty Mutual for about 15 years and was very satisfied with their prices and service, although I never filed a claim. When I retired and moved from California to Florida, my auto rate went up a ridiculous amount, to almost $10,000 a year even though I had no accidents and one minor moving violation in the last ten years. On top of that, Liberty Mutual screwed up my umbrella policy and told me it was “unenforceable,” whatever that means, but I had to pay for the policy anyway up to the time I canceled and switched to Progressive, which cost about one third the cost of Liberty Mutual for an identical policy. Even good companies change over time.
