Oh yeah, Kent is the man! Think after all I'm going to go with the W115. Looks quite delightful. Only disadvantage to the W115's are oil and fuel filter changes are difficult and messy and the unreliable Vacuum door lock systems. Other than that from what I'm hearing handles almost like a porche, if maintained can last just as long as a W123, and looks like nothing else.

^ Agreed. You're lucky that you're based in the States - I can't find a Diesel with AC in the UK anywhere - the few that do come up for sale are rusted beyond repair

Just picked up a W115 76' 240D a few months ago with the help of Screwdriver!

I took a stab at fixing my own vacuum locks, it certainly can be done, but difficulty really depends on where your leaks are. Information that'll help you:

- Ken at mercedes source has a great manual on how to test the system
- The mercedes factory shop manual (now on CD, google it) for the w115 has a full diagram of the vacuum system (80-901 in the manual)

If you just have bad rubber diaphragms on your vacuum actuators, there are 5 that comprise the vacuum lock system, then you're in good shape. But make sure to pull out the actuators, golf tee the hoses, and test all of the lines. The lines are a hard plastic hose that over time becomes very brittle. Mercedes did a good job of making it accessible in places where it gets flexed (in the door jams), but in other areas you may have to remove a lot of interior to get at the tubing (interior b pillar trim, rear seat back, plastic door thresholds).

So really test around the car with a vacuum tester to get an idea of where you're leaks are. Once you know that, evaluating the amount of work to be done becomes a little easier.

I pulled out all my actuators, replaced the rubber diaphragms, and put them back in only to find out that I had leaks in broken sections of the plastic vacuum hose. At that point I abandoned the project because I had to focus on more important repair tasks. When I redo the carpeting in the car I plan on re-running all of the plastic hose.

Also the heat/AC system relies on two other actuators to function. You can access them from underneath the dash. Make sure to remove your seats because it can be back breaking work to get them out.
