If you live in the USA, you are bombarded with TV and radio commercials for car insurance. Flo, the Geico Lizard, the General, and the Elephant are always plugging their company's products. I hate most of the commercials, but I digress.
Recently, I bought a new little commuter car. Previously, I noticed my Allstate car insurance was pricey, but I was afraid of switching, since I had our home and a big umbrella liability policy with them. For the new car, I did go to the Progressive website and get a quote, $200 for 6 months coverage (the most coverage you could buy). I then called Allstate who quoted around $600 for the same coverage. We tried to get Allstate down, but only by about $50. I then inquired whether my Umbrella policy would cover me if I went with Progressive for this second car, assuming I got the maximum coverage from Progressive. The answer was "yes" (grudgingly).
So I went with Progressive and am saving about $800 a year. Unfortunately this may encourage them to run more of those annoying commercials.
