Any other Euro owners? M110 with Manual?

Greetings,
I have been overly satisfied with my recent purchase of a very nice 1985 280SE. Temporarily repaired the front sway bar problem and now the car handles great. I have also been impressed with the performance the little M110 and four speed combination returns. Does anyone know what the gear ratios are on these cars? I beleive it is at least a 4.10 as the engine is turning a little over 3,000 rpms at 70 MPH. How are your cars equipped? Mine was originally built without factory a/c but was equipped with a dealer installed unit that utilizes a Sanden style compressor! The car does not have speed control but is equipped with manual rear windows, manual seats, ABS, and MB Tex. Still has its Euro bumpers, manuals, first aid kit and trunk mounted triangle.

The little M110 still has over 2.5 bar of oil pressure at a hot idle of around 600 rpm even with 200,000 miles on the clock. Need to adjust the valves as it is over due and it is rather loud at idle. How long are these engines good for? Any high mileage owners? Any input would be helpful.

Thanks,
Aaron
