A few weeks ago I had some car trouble. I needed a new part in my car before it could pass emissions. I’m an Internet geek with years of experience with things like web design, email marketing and SEO, definitely not a mechanical hotshot.

So when a friend offered to help I was completely relieved to forego the dreaded repair shop and more than thrilled that I wouldn’t be paying their rates. My friend is mechanically inclined and has a good set of tools, so I was confident that I was in good hands.
