not that it's more money, but likely items in the wx8 are components from helicopters and planes, something the company is known for is being aeromotive. the original name after the 70's was Vector Aeromotive. its a way to spread costs around.
i do know that gerald weigert makes jet ski's, and that company does very well.
would it be a good investment, honostly it's 50/50, but likely a smart idea, with more buisness mogals making upwards of billions of dollars, it's convient to not just have a leer jet but maybe a chopper to get around
