How long do these W126s last? More specifically the 560SEL. Can the engine and transmission be expected to be running smooth up and above 250k, 500k+ miles?

Heat and for some of us humidity or the lack of. During the summer months here it's not uncommon for temps to be 110F or greater with the humidity in the 4-5% range. Dry rot can be a big problem. You wouldn't think it would effect rubber parts like vacuum connectors but it takes its toll. I agree with you that heat/heat cycles is likely the number one suspect.You do seem to have a lot of vacuum problems in the US. I have come to think it must be the heat? Its all I can think of, we just don't get the same problems here in the same way.
We have a new car every three years at work and I've been here for 12 years, every one of those bar one, has been a pain in the arse. They all basically started and worked, but there were hesitations, electrical problems, broken air con that was never the same again even when repaired, continual trips to the garage and having to get the train home.
The limo service that I work for in Toronto also likes to get new cars every 3 years and a few years ago when they stopped making the Lincoln TownCar decided to buy/lease 10 of the these 5 Series hatchbacks.
They're all almost gone now because of the high maintenence and repair costs except for this one which had T-Boned some idiot that ran a red light.
It's being used for spare parts.
Almost all of his sedans are the Lincoln MKZ's along with four 'S' Series Benz.
