how much is a radiator

I was wodering how much it cost to replace a radiator for a 1996 3.8 M5 with labor. I just found out I needed to replace mine.

A new raidator is $120+ and labor should be $75 at most.
Who is dooing it, local guy or dealership?
And theres 2 kinds of local guy, the one every one likes and the SOB that does sh*t work and charges to much.
