Thanks, Martin, for the input.
When you say flawless, you certainly can't mean that it didn't need anything. I presume you did the normal stuff in terms of the failing suspension parts, transmission plate, etc?
I totally get the concept of cars needing to be driven. Cars that sit, especially with complex fuel systems, don't do well.
Thanks in advance.
I mean California to New York reliability-Just hop in the and go to New York today.. A W210 is a very reliable car over a W211 by 10 fold. I do not baby my car. I haul construction materials, and transmissions in mine. I love the self leveling function on these wagons. The other day I hauled 1,300lbs of Laminate Flooring-Filled the back.. I have hauled close to 1500lb of Lava Rock a few times from the building supply, and since I rebuild transmissions. I have had three 722.6's in the back, but the trannies are light as they weigh about 220lbs with torque converter each...The Next endevour may be a M119 long block for my buddies S500
When you get yours, Change ALLLLLL the fluids.... Change the coolant as old coolant can lead to head gasket problems. Use distilled water to flush and fill. Use Zerex G05 from Napa it is approved for the Mercedes Cars... Change those differential fluids. The transfer box is a separate reservoir; even though, it is the same fluid as the transmission, and is known not to be changed as frequent as the others. Change that thermostat too. A new thermostat just gives you better economy as the engine warms up quicker. New overflow tank cap as one needs to change that every few years too. I change mine every three to four years. I'd change the radiator hoses, and the overflow tank hose... Do not forget the hydraulic fluid for the rear suspension-Do a fluid exchange, but you may need accumulators on the rear rams(the shocks as everyone calls them). The shock function is done by the accumulators(they are easy to replace, and cost about $100 each-you need two, The are good for 50k miles or so)I just seek that California to New York reliability... The last one.. Change your fuel filter
Ahhh one problem the rust-belt people go through with these Self-Leveling cars is the valve, and node around the rear differential tends to get rusted-out, and one day you may find the wagon doing the LOW RIDER. Take a look at those hydraulic lines for the suspension back there, and the metal distribution block. The killer is you destroy your tandem pump up in the engine area because you lost all your hydraulic fluid, and did not act quick. The pump in the wagon like a W140 S500/S600 does two functions-Power Steering and Hydraulic Pump for the rear suspension.
All the best,
