Are you absolutely sure you want one of these cars? Parts are expensive, they are complicated, and they don't hold up that well. I notice you said.

"w124-Maybe I can drive it more than a week this time without something else breaking."

That's basically been my experience with my w124 too, and I wonder why you would want yet another one. I bought mine to replace my w123 300D, and I've had to keep it because it is so dependable compared to the newer w124. Go figure.
