PaulIt sounds to me like you did the right thing. M101-4/5 Marquards are not that rare. You'll find another, and probably won't have to wait more than a few months. And when you find it, it is yours essentially for free. You just spend the profits from your other deal, and you'll have cash left over.
Now, if you are looking specifically for a Marquard with a Standard Biscuit back, you may spend a long time looking for it. In that case, I can see why you would have some regret.
