Used engines

My vehicle is getting older and older, and I can tell that, very soon, I will have to either get a new car or replace the engine. Obviously, since the rest of my car is in satisfactory condition, it will be much cheaper for me to just replace the engine. That's why I have been hunting around and looking for used engines lately. I have come to know that I can buy used engines online for only a few hundred dollars. That's much, much cheaper than going to a dealership, because those people tend to rob you blind. Why go to them, when you can get quality used engines online? Moreover, such engines can surely last the life of the car, providing you get routine oil changes, watch that temperature gauge, and don’t redline the speedometer the entire family vacation. In case you don't find the used engine you need at a particular place, if the shop is well connected, they should be able to help you find you the engine you seek.
