I posted problems I had with my new 86 Mercedes 300SDL and I have a few problems and some general questions.

1. What are the RPMS I should expect to see at highway speeds (70mph is about 3000RPM on my Benz)?

2. My heater works great but the problem is, the heat only come out the lower vents (floor vents). I get regular air if not cool air coming out the upper vents (this is also the case with the rear air).

3. The temp control seems to take a little while to adjust to a new setting...is this normal?

4. Is it normal for a Benz tranny to slightly slip? It really is slight.

5. Is is normal to be able to change gears (from park to reverse and so on) with the key off and out of the ignition?

6. How easy is it to fix the mirror motor...my mirrors only go side to side and only on the pax side...even if I switch it to the DS, it still adjusts the PS.

7. Someone did a poor job of putting the CD player in and messed up the center console before I bought it...how do I go about putting it back together?

Thanks for looking, any other tips about restoring the interior would be greatly appreciated!
