When most people can barely dream of purchasing these new you're telling me they crush them after 5 years?
Yes. Just like similar armored BMW 7 series the Army and other groups have overseas. There is nothing "special" about them other than they are armored/added comms, etc. Anyone can purchase them. But DSS in particular dead-lines their armored vehicles at 5 years - then they become target practice, blown up and taken to somewhere to be destroyed completely. These are US spec vehicles modified by US armoring companies. It's pretty wasteful as these vehicles could be donated/sold to driving schools, etc. and get some use.
