In fairness most cars get taken for scrap with an engine which starts and runs. Even when they are running a bit rough it's more often fueling and ignition components than a mechanical problem with the engine components. That said, the synergy drive is by design a very robust mechanical system. It has no dog gears, clutch or torque converter. I'm sure this contributes a lot to their long life.
