I would think it more important to start the vehicle once a week and let
it run. Drive it once every two weeks at least. This  warms up bearings
and seals and keeps things lubricated. Otherwise, seals harden and leak.
Internal metal surfaces get drained of the oil coatings rom the last
running and are exposed to moisture in the air and consequent
condensation. Grease hardens and cakes up, resulting in loss of lub. And
particularly if you have Air Conditioning you definitely want to run
that once a week. If you don't you will come to a time - sooner than
later - when the seals are hardend and it will not hold the refrigerant.
Keeping the AC oils well circulated is important to maintaining the
condition of the seals.

You are better off running it frequently rather than changing oil and
filter frequently - in this case.

I've been using the calendar as my guide rather than the odometer and changing oil (20w50) and filter (Mann) every 4 months.  Is this excessive?  Would it be ok to drop down to 6 month intervals?  Seems like a waste of oil and filters when there is only about 700 miles between changes; but always think of it as cheap insurance...  Suggestions?
