My lust of the 140 is turning to a little sick in the stomach feel when I read what the owners are going through. There is a mint 124 400e in Ontario that looks brand new! They are asking a big$ for a 1992. As much as 1997 S class or 210. One big question did you sell your e55 and clk because of complex electronics? Are these "dealer only" electronics a way of making the car not cost effective long term? You have me thinking a newer 124 (mint) is starting to look a LOT better.
Many of the replacement parts for the 140 and later cars that are software and electronic focused are, indeed dealer only - OR available on the used market. The older the series, the fewer parts that are proprietary and therefore available by thirdparty, or by the original manufacturer under their name [such as Bosch instead of MB].
Even the 124 Series will have some of those parts. The wiring harness keeps going up in price, the ignition module is around $1400US now. The LH Module is near $1000 if i remember correctly. So, unless you go with a 60's era car you are going to get electronics BUT, the later the car, the more complex the electronics.
I sold the E55 because it had electronic gremlins that were a result of "over engineering" of the car. Much the same as when Microsoft adds features that are not necessary and cause unnecessary bloat in the system. The problems that my car had turned out to be across the line, affecting all E55s and was due to software issues.
To settle your mind, go talk to a couple of MB independent repair shops in your area. Tell them you are looking at a 92 400E and a 97 W140. Ask them what the book charges are for equal repairs such as getting the heads done, getting brakes replaced, getting the Fuel injection system replaced. See what they say. Also, see what they recommend between the two cars.
