wear and tear??....my 1st brand new 1981 Toyota Celica GT had 330k miles with the same clutch as well as my second brand new 1987 Civic Si with 220k, the rest of my cars were traded with at least 40k on the odometer, bought brand new and all but one were standard transmissions, now if something happens to the Z which again bought it brand new with 80 miles from a dealer as a 2013 leftover in 2014, I guess Mark E.Salomon will be on my quick dial...
