traits your Sim can have in the Sims Social. This trait is mainly focused on repairing objects, and is similar to the Handiness trait in The Sims 3. According to the in-game description, SuperMechanic Sims are:
- "The kind of Sim you could lock in a garage and they'd come smashing out in a car made of hammers."
Having this trait equipped means your Sim will fulfill +1 Fun every time they repair an object. High level SuperMechanics also will repair an object very quickly.
