Hi all, new to the forum, but from what I can see... it's a great one. I just inherited a 1980 300sd. The problem is in trying to start the car. I'm able to turn the key maybe a quarter turn in the ignition, I think right before the glow plug light would come on and it sticks, like there is something metal blocking the key from turning from that point on. I'll jiggle the key back and forth, move the steering wheel, remove the key a few times, say a few choice words, and eventually with a "click" the key would turn, and I'm able to start the car... It'll start fine a few times after that,... then it will happen again. It does it with both keys. Any ideas anyone as to what it might be? The only other problems so far, is the tach not working, which I remember a thread about that here somewhere, the left rear passanger lock not locking automatically (another thread I found) and the car being gutless, which from another thread might be a vacuum hose from/to the turbo? got to re-read that one... but you guys are great, lots of useful information. I'm hoping you can point me in the right direction on this ignition thing.

Thanks in advance
