Especially since everyone was running minutes financially these days, because all beginners, auto parts, where to buy cheap remanfactured, used items are available. Well, there is no simple answer. My recommendation - it depends on the side of the car it replaces.
If it is a gear or rack and pinion, which DONT rebuilt in most cases, anyway, you really have a choice. It would be wise to consider the history of the rebuilder and the level of processing. A good way to measure the quality of the company is looking for political security.
Other elements, such as suspension hub, struts, shocks, brakes, rotors, etc. always want again. Last thing you want is a spray and pray, and a few hundred dollars in labor plus the cost of reman. / Used to be glued part.
Apply the same philosophy your air conditioned car. The golden rule: You always want to buy new, with warranty, unless a new compressor is not available everywhere and refurbished is the only option.
The same goes for turbochargers and superchargers Buy New -. However, I noticed the quality of the reconstruction improves forced induction parts. Do your research. When in doubt, check your warranty.
At the end of the day, although mechanical, buy new, if not dont bother. Car radios, navigation devices and other internal components may be important, but usually do not stop working your car. In other words, if this is not the drivablity your car, shooting used to reman /. Pass the final script, you need your car to the Commission at the meeting of the company, because running is based on the mistaken party.
