I was in the office when coming across an ad of a car wrecker advertising a Mercedes car exactly the same model year like mine, even in the same color.

I thought I'd hit the mother lode and went instantly to the junk yard.
After 1 and 1/2 hour of labor, ruining my best office attire and my finger nails I pulled out following parts, all in good condition:
instrument cluster, what I just in dire need of
1 head light assembly (right)
2 tail lights
3 electronic modules in the relay box
2 sun visors
and some small parts like car jack, spark plug wires, first-aid kit, connectors, gas cap etc.
The awakening came at the register, they wanted $1415.- altogether. First I thought I was not hearing right then they showed me the monitor screen displaying the prices:
$192.- instrument cluster
$252.- head light assembly
$198.- 2 tail lights
$594.- 3 electronic modules in the relay box
$86.- 2 sun visors
the rest for the small parts.
Of course I went out empty-handed, would not think of paying such high prices from a junk yard, they are even more expensive than on ebay. I did offer $600.- but got no deal.
In the end I have worked almost 2 hours for them, removing the parts

My bad that I did not ask about their prices beforehand. I had thought to get the parts for less than 100 bucks each. I don't think that I would go to junk yards again soon. It's not worth the time and effort.
