These are some serious James Bond moves here.

This mechanic managed to save a vintage Mustang he was working on from being totaled after it rolled out of the shop not once but twice, first of all saving the door and then hopping into the moving car and pulling the emergency brake before it plows into other cars. You just know his inner monologue while all this was happening was 'Sh*t, sh*t, sh*t, sh*t, sh*t!'. Handbrakes man, actual lifesavers.
