Is this for real? On my '86 300E plugs and wires were part of every 30K maintenance. any thoughts?

I think your mechanic is wrong. The 100K interval is for M112 and M113 engines, which use platinum plugs.
1997 E320's have inline 6 M104 engines, which use regular copper core plugs. The replacement interval is every 30K miles.
