just purchased a c230 1998 in good shape with only 29k

I think I'll enjoy the car. However, no owners manual. I'd like a few explanations of features such as various light controls - pop out switch, etc., the small switch on the console with a round circle and a small figure, the S and W switch (summer and winter for traction control)... any other control tips appreciated...

also any ideas on where to get a manual at a good price???

thanks
