Don't know anything about the Mini other than what I see in the street.  The
first thing you need to know is EXACTLY what's included in the "basic
service" at the current mileage, including suggested or required spares.

Now, if you's asked about the original Mini, like, how to get into the back
seat without opening the doors or impaling yourself on the gear stick,
that's another matter <grin>. Or how to change the clutch without taking the
engine out.

Or how to keep twin 1.5" SU carbs in sync ... that's a trick question: it
can't be done.
