Ignition won't turn and is stuck in the "0" position. I think the tumbler needs replacing.
The tumblers are part of the ignition switch assembly on these vehicles. This part must be replaced as a unit. This particular part malfunctioning is a common problem on late 1990’s Mercedes Benz products. Have a mechanic who is familiar with Mercedes Benz diagnose the exact cause of your ignition sticking.
