Hi im picking up a 2001 172 tomorrow with 68000 on the clock everything seemed good on the test drive today just a couple of points need attention, 1st one is the speedo is reading too slow, would this be a sensor or the cable? Also there is no evidence of the clutch being replaced in the history and the bite point is pretty high, i was wondering how many miles the average clutch lasts for? cheers, kirky
