There is no definitive answer.
Anywhere between 15000 and 80000 could be possible.
Any car could do 25mpg with one driver and 35mpg with another.
The last 2 company vans I had went from new to 134000 on the original clutches and were both still good.
Does that mean all Peugeot Partner vans will do 134000 on the original clutch.?
