I have two Euro 240D's, one is the absolute cheapest bottom of the line and it still has vacuum locks. But WHY ON EARTH would you want to do away with them? They are VERY easy and cheap to fix. If you want to do away with them then just mechanically disconnect them.

Power windows are electric.

You will spend more effort converting all this stuff than you would simply fixing it when it breaks. I detest automatic doodads as much as anyone, but if I end with a car with all this junk on it, then I have made the commit to keep it working.

My Euro 240D that I and my son drove over a half million miles has hand crank windows, manual sunroof, manual heater/ac controls etc. The only gadget adder is an electric control for the passenger side rear view mirror which actually is quite useful.

All the manual stuff is one of the reasons the car was so trouble free for so long.

Good luck,
