It definitely varies for sure.
All the cars I've owned to date have been stick.
1987 Honda Civic hatch, sold it with 310,000 km, original 5 speed trans, and probably only the second clutch.
1990 Honda Prelude, timing belt snapped on me at 520,000 km, trans still shifted great but scrapped the car ultimately since it needed a bunch more work anyway.
1996 Pontiac Sunfire GT, great Getrag 5 speed, and the 2.4 engine was peppy. Too bad the rest of the car was awful. Sold it with 230k km, probably original clutch.
2003 Pontiac Vibe, 5 speed stick... Some bearings in the trans crapped out at 190,000 km, replaced with a 6 speed and replaced the clutch at 200k.
So yeah, it definitely varies. I'm tempted to say they don't build 'em like they used to.. I hope my powershift is trouble-free, so far so good.
