I must be a lousy searcher as I didn't hit anything with this.

I'm trying to clean 26 years of the PO's crud out of the interior of my newly aquired 190d automatic. Pulled the seats and snapped out the carpets that cover the flat parts of the floor. Stalled out attempting to remove the console as the shifter handle didn't want to come off. How does the handle fit onto the shaft? Is it threaded? Where are the bolts holding the console to the trans hump? How do you remove the remaining carpets up the sides or would it be easier to shampoo them in the car? Are there drain holes in the floor pan if I get some water in there or is that a bad idea?

Thanks in advance!
