What will you do when your car engine is broken down? Will you go and change a new one? Or, will you just get a repaired? As i know, the cost of repairing the car engine is always much more expensive than buying a new engine, so if i were you in the situation of car engine broken down, then i think most probably i would get a new one rather than repairing it. However, now only i know we can think of buying an used engine from midwest auto recycling where their used engines are test driven, visually inspected and cleaned. If used engine just as if a new engine but with more lower price, then it is really no harm to get the used engine.
