You are correct, the latter two sentences cannot be used. Made, in the sense that it is used above, implies some kind of coercion, in that somebody was forced to do something through an action of your own. Had, in the sense you use it first, is a strange one, and although correct it strikes me as an Americanism (but since you are Korean I am assuming American English is what you are used to). In that sense all it means is you arranged that a certain person would fix your car; there was no coercion, you and the mechanic agreed a date, and a time, and a fee; you had him fix you car. Made works for sad because somebody's actions resulted in the sadness of someone else.
