Used car parts ???

theboydiddy

What is your opinion on used parts ?
Reason why I ask, it is because I purchased my Z brand new and I feel like I should purchase brand new parts for it as well. It is only right. (I think)
But then again, I have friends telling me used parts are good. They're just used but can pull the same performance, or make your car look just as good. Then I have another group of friends who not only agree with me, but believes buying used parts it is just asking for trouble. You may save so money compared to a brand new part. But soon enough you'll have to either replace those used parts or have to fix them which after all prices would be the same as if I had purchased brand new parts to begin with. - I also like the "break in" part.
But what's everyone's thoughts on used parts ?
