I've had mine for about 7 yrs now, had the engine rebuilt when I first got it, use it everyday and apart from the clutch cable snapping a few times, headgasket going twice and the odd old bit failing on it like the water pump. Its been absolutely fine.
Till I picked it up last week, well its allowed to be tempramental every now and again, its not yet out of its teens, technically its a few months till its 20 yrs old.
I'm sure after a trip back to the garage it'll be all fine and dandy again.
