Hi Relaxo,
There is specialty insurance for that type of risk and you must qualify. Most collectors insure them as collectors items or antiques. If you are insuring something like a show car, there is also coverage for that with some specialty carriers, but once again they would have to abide by some rules, as they would not be able to be daily driven. They are fully covered, but the coverage is different, they aren't allowed to drive them as daily cars as well as some other rules that they have to abide by.
