You can throw them away, or you can put that money back into your pocket. As the old saying goes, "one man's trash is another man's treasure."

This is where the Internet, comes into play. With a little research, people can find high-quality used parts with little to no time and pay about half of what a brand-new item would cost.

Start by checking out various "classified-type" websites. One of the most popular and user-friendly is eBay. Through eBay, you can buy and sell old or new items anywhere in the world. For a minimal fee, this site lets you post pictures and include a description of your item, as well as allowing you to host the auction.

The next step is one of the most important steps of all-clean your parts! Take some time to wipe off all of the grease, dust and dirt.

Once the parts are clean, lay them out on a clean background for your photos. When it comes to the photos, imagine yourself as a potential buyer when you're taking the pictures. What sort of pictures would you find most appealing?

The next, and possibly most important step in selling your parts on the Internet, is your description. Tell it like it is. If the paint is chipped off or there are dings in parts like pipes and A-arms, let the buyers know. They know they're looking at used parts. Not everyone is expecting a part in showroom condition. There's nothing worse than having to deal with a disgruntled customer who feels they've been wronged. This will only generate more work for you in the end.

Once you have entered your description, post your pictures, and make sure to double-check everything before you post your listing. If you made a mistake, correct it before posting the ad. Be sure to post your listings in the evenings. You want people to be home and unoccupied, allowing them plenty of time to peruse and/or purchase your items. Another helpful tip is to prepackage your items for shipping. In the event someone asks you how much shipping will cost, you'll already know what size box you'll be using and how much it will weigh when you go to calculate it. That could save you a ton of time.

In no time, you will see how much your not-so-hard work pays off. You will gain garage space as the parts start to disappear and the dollars start to flow back into your pocket!
