This forum has more exposure than the parts forum so I am posting it here. There is a tune-up kit on EBay (dist. cap, rotor and set of wires) for 300E. There is only about 45 minutes left on the auction. There is only 1 bid so far for $135.00.
I am not involved in the auction....just trying to help out a needy MercedesShop. Item #1840179875
