High Point auto insurance was rebranded to Plymouth Rock recently but High Point is still the name of the underwriting company, and High Point underwritten auto insurance is offered exclusively in the state of New Jersey. Plymouth Rock even created a separate website for its New Jersey customers with unique information and articles specific to the state. High Point was recently downgraded by A.M. Best for various reasons, and has received lower than average customer satisfaction ratings from J.D. Power, therefore it may not be the best option for auto insurance seekers in the state.
