I was shopping for car insurance this past summer, and being only 20 at the time, I found the prices were pretty much the same for each company. I ended up with State Farm, because of my friends prior experiences with Allstate and other companies. State Farm acts faster during emergency situations such as accidents when you may really need them. While Allstate gave my friend the run around when he was slamed by a BMW, and the other driver admitted it was his fault.
