If you perform the calculation by looking for “used car engines for sale” on Google, you will be astounded by the vast difference in pricing between a used engine and a brand-new one. It may cost 10 times as much as a used engine. Don’t you think the pricing difference is ridiculous? What are the benefits of installing a new engine in your existing car? You may not be able to use the full power of the engine since your previous car may have died totally. However, a used engine will exceed your expectations for durability.
