My grandad managed to ruin a clutch in his brand new Aygo in 8k (he's deaf so can't hear the revs build, so simply mashes the throttle and lifts up the clutch incredibly slowly).
Equally, one of my friends has had 3 clutch replacements in her Clio and she's only had it a couple of years - it doesn't surprise me at all that you can ruin a clutch in 30k.
The first gen / run of Aygos were notorious for eating clutches. Thread here from last year with a couple of us discussing it.
