I need your opinion on Labor cost on my 1986 560SL.

I'm been charged $1900.00 in labor for a complete Front suspension update
Upper Control harms (expensives!)
Shocks
Engine Mounts
Sub-frame mounts
Steering damper
Ball joints
Tied Rod
Drag Links
All bushing kits
and 2 Flex Disc in the rear

The total bill around $2800 with parts. What do you thinks?
I'm in Miami, FL

Thanks

Jorge
