My 1980 race car is insured for 112 dollars a year. That is basic liability. Too meet state laws, making the 'race car' street legal with registration. This does not cover accidents on track or off. Street legal to drive to a local track event or a trucking company for out of town events. It all depends on how much coverage you desire. For example, my street cars are covered for glass. Arizona highways eat windshields. I am allowed 3 windshields a year. Nooo deductible. Shop around, decide what you want and need.

It depends who you go with. It can cost anywhere from 150/mo to 400/month. http://autoinsurancey.com/car/porsche-911
