If I really have to make a choice, I will take the 560SEL instead. Seems to me that the 500 still has lots of problems, and we are not sure how much work were done by the mech.

Also i do feel $2500 is too high for both cars, it got over 200,000miles and the condition is uncertain. These cars can be a money pit if you have no idea about its service history.

I have a 560SEL and i can tell you the sound from the rear is the fuel pump. It is normal if you hear some "zzzzzz" sound, if it start crying that mean the fuel pump is going south... also 560 has 2 fuel pumps, one of my fuel pumps died when i was driving and my car cannot go over 80mph(feel lke having a speed limit control)

for the hydroneumatic suspension, i dont need to rev the engine to 3000rpm to make the rear raise, i got 2 big adults plus 3 suitcases at that time, once i start the engine, i saw the rear is raising up instantly. but if that car doesnt sag, also the PO may switch the hydro sus back to the basic one 420SEL has.
