Turning 50...
Next up I'm told spark plugs (how many are there in total?) and V-belt are individual items I would want to change in a few thousand?
How much should these two cost? $450-500 if done together?
What else did you encounter that is not in the normal schedule? Ball joints? Suspension? Steering components? Bushings? - are there upgraded AMG parts/E parts we can utilize to stiffen up the suspension on the 550?
