I've been with American Family Insurance for my Auto and Home policies for about 11 to 12 years now, and I am very happy with their service! My policy covers all the basic auto coverage, plus they offer a LOT of optional extras. I have a few of the optional parts of the policy including towing and car rental if you have an accident and you need to rent, but they offer an extensive list of optional coverages. Their range of deductibles and amounts of coverage are very nice because you can tailor your policy to make it affordable for you while keeping the parts you really want and lowering the coverage on other things. They give discounts if you have any kind of alarm system, special key for the ignition, air bags, etc. You also get discounts for good driving and for having other policies with them (for instance I have a home policy, too).
They offer competative pricing for the policies, although they may be a bit more than the discount policies offered on tv and such. The service makes it worth the extra $5 a month I might pay, though-Any time I've ever had any kind of a problem, I call and it's immediately taken care of. I had a no-fault accident earlier this year in a parking lot where we backed out at the same time right into each other-I called the number on my card and the agent told me exactly what to do and what would happen. It was quick, easy, and it made a very minor situation STAY a very minor situation-that's so important when something like that happens!
Another great thing about this policy are the payment options. You get your bill-you can pay the entire amount for the year, 6 months worth or a month worth. Each payment other than the full amount is a $2 fee. That's really reasonable when you just need to extend your payment a little bit-maybe you're short that month or you just have enough for 6 months-they give you that option. Also, if you're a little late it's not the end of the world ;) They keep your insurance current and don't charge a late fee.
Overall, these guys have been great for me-I know this will vary agent to agent, but I would certainly tell anyone to give American Family a chance when you're looking for car insurance!
