Whatever you do, make sure you have enough coverage and then some.
Lets say someone gets a Pagoda $30-40K, and gets it insured for the $30-40k value you paid for the car. Next you start making improvements over the years, the "rolling restoration" engine rebuild one year, paint the next year, interior a few years later,,, as the years pass the car is worth more and more and you forget to increase the insurance coverage, you just pay the insurance bill once a year an move on. Most of us would not think wow, just got a new engine rebuild, car is now worth x more than I paid for it, need to call the insurance company and increase coverage - this does not happen in the real world, unless you work in the insurance industry in some way - no different than if you remodel a small bathroom in your house you typically would not call you home owners insurance and tell them I just remodeled my bathroom my house and my house is now is worth x more, please increase my coverage & and send me the bill for the increase in coverage, it does not happen.
Next thing you know the car you paid $30 - 40k for a few years back is now worth $110K, but you do not realize that you still only have $30-40k insured on the car, and then the unthinkable happens - accident with a under insured or uninsured driver, your car has $60k damage, insurance will only cover the $30-40k you have on the policy you been paying on since the day you bought the car, who pays the difference - you do !!!! Parts and labor are much higher today than 10 years ago, so your insurance policy of 10 years ago will not be enough to cover any significant damage with today's rates.
Don't ask how I know this, just hope it helps one person in future, just learn from my mistake.
