Diverse problems with 1984 190e 2.0 European version

[efutch]

Hi, I recently purchased from my father-in-law a 1984 190e 2.0 with only 65,000 miles on it, but I have some minor problems that I wonder if someone else has experienced them:

i) The ignition key sometimes doesn't turn and I can't start the car! Seems like the steering wheel lock "locks" the switch so hard that I can't turn the key...I have left the car in a shopping mall parking lot because I couldn't start it.

ii) I have to add brake fluid every week, maybe 1/4 of the clear plastic reservoir in the motor trunk. Is this normal?

iii) When it rains, I get water on the back trunk side compartments. I have read about water in the trunk on other sites but they mention something about the glass rubber seal. I don't think this is coming from the glass.

Please bear my English, and I could clarify some items if anybody needs it.

Best regards,
