Ive done very low mileage, somewhere around the 32k mark, clutch is mainly had it because of my brother, everytime i go abroad, he takes the car out and attempts his "tokyo drift" rubbish and what-not. If the car is driven well, then id suspect the gearbox would last a long time.
Having said that, my mates Zed has done 89k on the clock, hes on his 2nd clutch, first one was changed after drift lessons at 57k on the clock.
