Because you're in Florida, prices are different in different states and counties. Mercedes repair cost are high anyway, welcome to German.
I finally talked to the guy that had the car and it is the oil drain bolt that leaks at times. Do the make the oversize drain bolt that re-threads itself. It has been over 20 years since I was in business and we could find those bolts for american made autos. Any suggestion?
They're available still.
