Ted Corless, an insurance-litigation attorney in Florida with the Corless Barfield Trial Group, which has dealt with many sinkhole claims, suggests the museum would be better served if a geotechnical engineer made an evaluation rather than a structural engineer.

He says the structural integrity of the building itself may be less of a concern than the state of the ground beneath it, specifically citing the risk that attempts to fix the one sinkhole could trigger others, resulting in further damage. In many cases in Florida, he says, a large sinkhole will be “the first of what will be other events.”

He also says that attempting to extract the vehicles will be a “very delicate maneuver” that could result in the loss of equipment that will be used around the sinkhole.

Regarding potential coverage for the Corvettes, Corless says any payout would depend on the type of coverage and whether proper assessments had been made on the actual value of the vehicles. He also said deductibles could be considerable, noting he has seen specialty policies with deductibles up to 10%.

But Jonathan Klinger, public relations manager for Hagerty Insurance Agency, a leading provider of classic-vehicle insurance, says high deductibles are a “common myth” when it comes to classic-car insurance.

He stresses that Hagerty does not insure the National Corvette Museum, and that he does not know what coverages are involved in this particular case, but he says individual classic-car policies insured through Hagerty often have no deductible. For commercial policies, which would be more common for a museum, there are “many different deductible options,” ranging from zero up to tens of thousands of dollars.

Regarding available policies for classic cars on display in a museum, Klinger again notes that he doesn't know the particular coverages involved in this case, but says Hagerty offers museum-specific coverage for classic cars, and, whether the cars are on loan or owned, they would be covered to an agreed value, which is determined beforehand by the insured and Hagerty.

For cars on loan, such as the two in the museum that were on loan from GM, Klinger says payouts could depend on what type of coverage GM had. But a museum with coverage written through a Haggerty policy, he says, would be covered, and a decision could be made later by the insurer regarding possible subrogation.

Corless wondered if damage by sinkhole would be covered for the National Corvette Museum, saying that, in Florida, he has seen policies that include such coverage and those that would exclude it.

Klinger says that, in Hagerty's case, sinkhole damage would be included. Furthermore, he says the entire loss would be a single event, so the deductible would apply only once, versus having to pay the deductible on each vehicle.

The National Corvette Museum did not respond to requests for comment.
