IIRC the 617 drain hole faces aft and is quite a reach. The '87 300D drain hole is on the side so I can reach the plug without lifting the car. Extract or drain, I don't see much of the underside so I need to plan purposed underside inspections. Ironically or conveniently, the front belly pan has been off for the past few years while I keep track of a front seal leak.
