I'm in the army and currently stationed in Hawaii. Specifically in Oahu. I'm about to buy a used 2014 Ford Mustang. I have an excellent driving record and credit score and the car has a very good history. I'm looking to get full coverage for myself and other possible drivers of my car at a fair price. My question is, will I be better off looking at local insurance companies or try the national chains like Geico or State Farm to find the best deal possible?
