Fame

There are a few ways you can become famous as an auto-mechanic: If there is a reality show about your family and you happen to be an auto mechanic, or you become famous for something else. You probably won't be famous for just being a mechanic. 

You can be around famous people if you make it to the Pit Crew of NASCAR (you probably won't), but you still wouldn't really be famous. If you work in a small town, you'll be famous among the 500 people who have no choice but to take their business to your shop, though.
