I've wanted a Porsche for a very long time and recently came across an
early 90s 911 Cabriolet for what seems like a decent price. One thing
I've noticed is how many cars I'm finding with 60 - 80k miles on
them... is there some major service required at this mileage that is
causing people to sell their Porches rather than get the maintenance?

I've been searching for maintenance schedules for various models and
haven't found much.

Any help would be appreciated.

60K mile service recommended.

There certainly is. The 3.6l motor uses rubber gaskets that shrink
over time. This wouldn't be such a terrible thing if you could
tighten the bolts up and squeeze them a bit more, but the bolts which
hold the engine together are shouldered so this is not possible. At
about 60k they start leaking a little from one cylinder-case seal, or
a thru bolt, soon enough they will all be leaking. Eventually the oil
is flowing freely. The rebuild takes about 45 hours and the kits are
about $500 (I think). Its worth doing the rings while its all in
bits.
I did one recently and it cost me $5000 (Australian dollars)so US
$3000.
The climate control is also a problem area.
