Diesel mechanic near Downtown L.A.

Hi,

I've recently moved just west of Downtown L.A. to get my B.A. at USC.
I need a mechanic to service my 1980 Mercedes diesel.  Anybody know a
good, reasonable mechanic in the area?  The car is a beat-up workhorse
so I don't need a factory trained virtuoso who will wrinkle his nose
at my "ghetto benz."  I only have one car, so I can't leave it in the
shop for weeks at a time.
I'm not a haggler, just don't like somebody pushing very expensive
work on a $1,500 car.

Thanks!!
