Auto mechanics must stay up to date on any new technology that is being used when building cars. This means learning about engines that run on alternative fuel, as well as innovative features and upgrades.

Successful auto mechanics must be focused and detail oriented. They must be motivated to figure out a problem and then be able follow the necessary steps to fix it. Auto mechanics must be able to estimate the time it will take to fix a problem, and then work within that time frame to complete the work on time as promised.
