Erie is a good company, don't know how their rates compare though. I too am a GEICO policyholder. Pretty easy to get a quote at GEICO.com or call them. This is Warren Buffett's company, or I should say Berkshire Hathaway owns GEICO. Haven't had any accidents that I've really had to use them (knock on wood) and test their customer service. I have 7 cars in total (3 Benzes...all 124's, 1 Infiniti 1994, 2 Hondas, & an Acura) and 5 drivers of which three are kids in early 20's with GEICO. FWIW, on one policy I have 2 Benzes, the Infiniti, and the '03 Honda and pay $90 per month. Going to add the third Benz to the $90 per month policy, so that policy will obviously increase from that level, but my guess is by only $10-$20 per month. One nice feature, if you have kids living out of state, like my wife and I do, you can have separate policies for them, but still have all under the GEICO umbrella and get a discount. The other Honda and the Acura are separate policies because those kids live out of state. Would have to look up the rates, but they are definitely more expensive because of the age and newness of the Honda & Acura. Hope this helps.
