Used Auto Parts That Are Never a Good Idea

Before you decide to install a used auto part from this category, check your head. Most of these are parts that wear with mileage and are probably well on their way to uselessness as you're putting them in. Used auto parts can be great, but unless you're in Cuba sometimes they're better left sitting in the stinking yard of the used auto parts junk spot than installed on your car. Any used auto parts outlet with any integrity wouldn't sell you these parts used without at least letting you know that it might suck.
