Pity they're all out of service, still, I suppose there's only so far you can take a single design before you're either effectively building an entirely new tank or fiscally better off buying some of the tons of surplus armor that's out there now - T62, T72, T80, T90, M60A3, Leopard I (or II!) or even M1 Abrams if you can afford it and the operating costs.
