Louis,
This is very good info. Thanks!
DDH, the $300 figure includes the 4 new glow plugs they've already installed, other checkup (battery, starter), plus the valve adjustment and compression test.
Any way, I'm going to have them do the valve adjustment and compression test. Hopefully, the car will start again. BTW, this is an incredibly great forum with knowledgeable benz enthusiasts. I'm glad I found this site. Thanks all again!

A diesel doesn't have sparkplugs to
ignite the air/fuel mixture(glow plugs don't
ignite the air/fuel mixture,they aid in heating the
incoming air ),it does this by compression of the
air in the cylinder,where then fuel is injected at
the correct time.
Now if the valves are open at this time
the air won't be compressed thus not creating
the heat needed for combustion escapes.
No combustion=no compression=no start.
Also when it is cold the incoming air strains
this process making it harder to start (that is why
when the engine is warm it will start)
The valves are adjustable,so they get out
of adjustment after some time.(they won't
open when needed or stay closed when
they need to be open).
