Erie is the cheapest insurance company, and arguably the most reliable insurance company as well. They score points by allowing customers to start their quote online, which we personally found to be a streamlined and fast process. Erie also scored the highest marks from the number of policies they offer. Erie offers pet coverage, free accident forgiveness, free vanishing deductibles, roadside assistance, and many more, essentially giving its customers a degree of flexibility not even found amongst the largest insurers. Customers of Erie may also be eligible for its Rate Lock program. This is a unique program where customers won't see their rates increase except for three reasons: you move to a different area, add or remove someone from your policy, or add or subtract a car. Lastly, despite its smaller size, Erie offers the same types of discounts larger national insurers provide such as bundling, anti-lock brakes, anti-theft, young driver and senior driver among others.
I have had Progressive for years and have never had any trouble. My car got plowed into by a deer, and Progressive was reasonable to deal with. Their rates are also about the best I can find. We bundle in our home insurance (through some licensed third party) and save even more! Our rates just actually went down this past 6-month period which was a pleasant surprise.
Safeco is not the best, but if you have a classic car you want to drive as your regular vehicle, Safeco is the insurance for you. Safeco allows you up to 10,000 regular use miles which is similar to what someone may drive on a normal policy. Most collector of cars are not looking to drive them regularly, but if it happens your 1968 Ford Mustang has to be your premier car, Safeco is your best bet. The limitation to Safeco is its stricter list of vehicles it will insure, including a ten year required minimum.
