Cost of maintenance/upkeep for a Chevy Corvette?

[Bob]

Hello, I was looking to buy a Corvette from the 70s to 80s, any type really. I was wondering what the average maintenance cost would be. Just give me a range. Does insurance pay for the upkeep? How much money (and time) do you think I would have to spend yearly?

I was hoping for a range of how much it could cost (for any type from this time period), but if you must, please assess the max/min amount of money it will cost to upkeep this example:

I have a 75 and as a retired Master Auto technician I can only estimate what you would have to pay if you took it in for all the service. First of all the worse thing to do is to park it and only drive it once in a while or just run it for 10 to 15 minutes every week.
If you want to keep maint cost down DRIVE IT! The more often you use it the cheaper maint cost is as seals - bearings are lubricated and condensation is burned out of the crankcase too! If you drive the car maint costs are about the same as any other car.
If you just want it to store it, just keep extra money in the bank for it !
