I've been looking at buying a new car. I've got it narrowed down to a '11 Mustang GT, or a '08 Mustang GT500. My current insurance company (Geico) was going to charge me an arm and a leg, so I decided to start shopping around. Progressive was about $30/month cheaper than Geico, and All State was about $50/month cheaper than Geico. Have you had good or bad experiences with either of these companies? Any suggestions for other companies?
