Are these repairs costs normal?
 

1995 Mercedes S320:

Differential bushing/s and labor: $192.00

Oil change and filter: $95.00

Antifreze, flush and thermastat change $180.00

Replace rear shocks (non-air susp) $520.00 ... parts/labor

Replace head light lense (labor only) and install
to H1 bulbs. I furnish lense & bulbs. Labor only... $170.00

What do you think of these charges? I think they are
a little high.

I had purchased a drivers side lense and took this
and two new bulbs to the shop. Went to pickup
car, cost $170.00.

Your thoughts? Shop says he charges $85.00 an hour.
