I am thinking of getting a "topside" style oil change pump (to avoid getting under car) for a 1985 300D. Have there been any problems with getting the tube all the way in on this car? Any body use one?

Also, I was curious about this electric motored version (12V). Anybody heard anything positive or negative. Only 22 bucks.
