The Auto Carrier's Insurance kicks in at that point. Been There, had that happen. A whole load, and 2 months later a Fixed Focus showed up that we had to refuse. Full Disclosure here in Ontario Canada. We couldn't sell it for New only Rebuilt. Manitoba Insurance rebuilt it.Not likely. I can't speak definitively about the tornado-damaged Corvettes, but this issue came up some decades ago following a similar situation. The situation was a car carrier crashed destroying its cargo of new Fords. A reporter asked about the insurance on the cars. The spokesperson explained that the insurance premium did not make business sense in view of Ford's replacement costs for the destroyed cars. The average car buff does not have a clue about manufacturing economics and their relationship to the drive away price paid by the retail customer. Most believe that the manufacturer's costs are dominated by metal and labor. This is not the case. It is not even close. This is truer today that it was when that truckload of Fords bought their tickets to the wrecking yard all those years ago.
