Repairable--maybe so but why start out with a bus that clearly has been run over some rough roads. I wonder how many other cracks and failed spot welds would be found if the bus were systematically taken apart.
I'm surprised that the auction is offering that bus for sale to the general public. Vehicles with that kind of damage are usually sold only to licensed dismantlers.
As the Brits would say, "She's a pretty face but she's a bit of a tart".
