I know the dealer in our area bought a new Hunter alignment machine as per Mercedes requirements and I believe the cost was right around $250,000. As I understand the machine was designed specifically for Mercedes, to Mercedes specs. If I paid that kind of money for an alignment machine, it would take quite awhile at $150 a pop to start showing a profit.
