A seemingly odd question
check out Grundy, that's what mine has. mine is like $65 every 6 months. you aren't supposed to use it for daily use but they don't care if you drive it around. they said that if I have kept the car this long it's evidence that I intend to take care of it. also see if your parents will add it to their policy and add you as a driver, it's usually cheaper that way too.
anyway Grundy is the most reasonable of the collector car insurance. seriously though I remember when my insurance was several hundred a month on my '71 Cuda with a 440HP. it was extra because it was a hard top, it was extra because Cuda was a sports car, it was extra because of the 440, it was extra because I was under 25, and male. wish I had that car now, I could retire!:-D
