I am with Nationwide/Allied and Just filed a complaint.. HOWEVER, my case is a bit odd.
The complaint: Under the law both here in Michigan where I officially live and where the contract (policy) is signed and based, And in South Carolina where stuff happened.
IF you buy a new or used car, or RENT a car, and you have an existing automobile which is insured, said insurance extends (For a period of days) to the new purchase/rental. That is the standard of practice across the industry and the law from what I am told.
NATIONWIDE refused to cover the Jeep my wife crashed 2 business days after we bought it. They claim a Class A motor home is NOT an automobile.
So, be aware of that.
IF you have a 2nd vehicle (Towed) you won't have a problem.
If you do go with Nationwide, I've been very happy with them save for this incident.. And feel free to pass this post to your agent.
