I shopped around for the best price for the coverage I wanted and Progressive undercut the others by around $1200. Every 6 months my monthly premium goes down. After the first six months we added another car, and the premium only went up by $6 because the policy dropped by such a significant amount. They've been good at getting my documents to me quickly, and having 24 hour customer service - which I'm coming to appreciate more and more with the odd hours I'm awake and work.
Safeco is not the best, but if you have a classic car you want to drive as your regular vehicle, Safeco is the insurance for you. Safeco allows you up to 10,000 regular use miles which is similar to what someone may drive on a normal policy. Most collector of cars are not looking to drive them regularly, but if it happens your 1968 Ford Mustang has to be your premier car, Safeco is your best bet. The limitation to Safeco is its stricter list of vehicles it will insure, including a ten year required minimum.
