Hail that size will total a car in seconds.
I once saw a car that looked like someone beat it over every square inch with a hammer, after a very brief Hail storm like that.
East Tennessee had hail like that a few years ago. The car insurance companies set up temporary drive-thru facilities where you could have your car inspected and start your claim with an adjustor. They were packed for weeks. You still see cars in that area with hammered looking sheet metal.
I had a RAV4 that was totaled by the insurance company for hail damage, paid me $4,200 and let me keep the car. Within a year almost all of the dents had popped out. What few were left could only be seen if you really looked hard for them and they could not be seen in photos. For some reason the insurance company never noted in the records that it had been totaled. I kept the car another ten years and recently sold it for $3,700.
Looks like we had similar experiences, VerySadAmerican. :)
