Some of those prices seem pretty high. What year and model is your car? Also, are those prices inclusive of labor?
To give you an example:
I had a shifter bushing replaced. Part cost $10.
Motor mounts for my C43 are about $75 each.
I paid around $450 for my Koni adjustable shocks.
Also, I have one side for lower control arm bushings. Brand new and unused, $30 +shipping. Note: you will need two sets, and I only have one.
