yea, i noticed with my 87 300D that when i had the plastic sound proofing layer off (for a while), i could kinda squat and reach under and get the plug out and the oil pan would fit under. i didnt have to lay on the ground. if it wasn't for that sound barrier plastic thing (which i think i one of the neetest parts of the car) i could do an oil change in like 15 minutes, easy! as for now i kinda lay uner there and admire the engine
and it can take me up to 40 minutes to do the oil change.
