I think most, if not all, of the techs on this site have commented on how hard M119's are on distributor cap and rotors.

If I had an R129 / W140 / W124 / W210 with an M119, I'd change them at 60,000 miles intervals, along with the wires.

I have read comments on how darned expensive a set of cap / rotors /wires, are though.....
