How do I calculate my car’s equity?

My husband is an accountant for the Ford Motor Company, and I like to quiz him about how many cars and trucks they sell. He always moans “I’m not that kind of accountant”—he handles staff payroll, nothing to do with cars. But my husband recently pulled up in a used (but you wouldn’t know it) 2014 Ford F-150 Limited pickup truck, that is just as swanky as you can imagine! How many Ford F-150 Limited trucks were made in 2014?

I was in an accident recently that severely damaged my 2019 Jeep Grand Cherokee Limited’s gas tank, and it’s looking like I’ll need to have it replaced. How much does it cost to replace a 2019 Jeep Grand Cherokee Limited’s gas tank?

I live in an area with a lot of tornado activity, so I'm worried that some time down the line, my house may be destroyed and need to be rebuilt. In that scenario, how would an insurance company decide on the cost of rebuilding?
