When you need something fixed or modified on your car, who do you trust to get the job done? Your local mechanic? The expensive guy? Your friend's friend? While that last option is acceptable in some cases, the only real answer is none of the above, because the only person you can truly trust to touch your wheels is you. So get that wrench ready and pullout the welding kit, because you're about to DIY this thing with the tools on hand and nothing more. 

Doing something yourself is an integral part of the blue collar modification experience. Not only is it the cheapest option, but you don't need anybody else to buy into your vision, and you can show off your handy prowess to the whole world when you're done. Also, if things get messed up, there's nobody to blame but yourself. 

Cars are perfect for this kind of modification. Not only do they need constant fixing, but there are so many parts you can swap out. Not to mention that once you're done, you can show it off by just driving around. Hopefully everybody likes what you've done with it. Here are 25 awesome examples of blue collar motor engineering.
