Unable to start engine. Turn key, no click, no engine turnover. Symptoms always occur in Park, but if I shift in to neutral, engine will start on 1 out of 3 tries. Anybody know what's causing this?

Could be in the shifting mechanism. Although this talks about the reverse lights, it fixed the same starting issue on our 1999 SLK 230.

Have you seen if your reverse lights work?

I asked how old battery

Give the starter motor a few hard taps, could be the solenoid on it's way out?

From his explanation. I definitely think it is the neutral safety switch.
