An interesting factor to consider in engine life, using mileage as a proxy, is the rear end ratio. Some Mercedes have 3.69 rear ends, while mine has a 2.47. Assuming the same size tires that would mean that one car with 300k on the clock would be roughly equivalent to another car with 200k. Typically the car with the higher rear end number will be revving higher at any particular speed thus putting more stress on al moving parts, so the effective wear equivalent would likely be even higher.

If engines came with an absolute rotation counter it would be interesting to see how many cycles these engines would actually make over their lifetime.
