My 85 300D has begun to show signs of an ignition switch issue, I believe. Over the past few weeks, it has intermittently (on occasion only) not turn off (glad MB put in the emergency kill switch on the linkage) and not start (I had to turn it "off" and remove/reinsert the key to get it started- but only once so far). It also seems to hesitate sometimes before kicking the starter over.

Is this a soon to be dead ignition switch? If so, do I just replace the whole mechanism? Anyone know how much they are from MB or do I chance it at a junkyard?
