I just bought a '70 280SEL from an acquaintance as a HS graduation present
for my daughter, and I now find myself in the dubious position of taking
care of it.  Since she's off to college in the Fall, the car's going to be
sitting covered in our yard for nine months out of the year, apart from
maybe driving it to work once or twice a month just to circulate the oil.
The car has 160K miles on it.

This is my first experience with a Mercedes, I'm a reluctant mechanic and
have never tried to keep a car this old running.  It came with a cover, and
I've bought a "garage-in-a-box" to keep it in.  Plus, the gentleman who
sold it to me gave me about an entire U-Haul van worth of parts - an
engine, tranny, 4 doors, window glass, several body panels, an entire
upholstery set, etc. - I'm guessing these were salvaged from a second
vehicle.

My question is this: what habits should I get into with this vehicle
regarding lube, oil changes, and any other maintenance that Merc owners
take for granted but a newby like me is likely to ignore?  I am afraid to
take the car to Jiffy Lube for things like oil changes, since they pretty
much treat every car the same and I'm guessing that this one needs special
handling (17 lube points for example).  Any opinions?

By the way, some photos are here:
