Mechanics should have more frequent opportunities given by the game to do their job, even outside of "mission hours". Not sure if this ties into the bug report I made recently, but I still want to post it.
Basically, any unoccupied car that's never been touched out in the game world could randomly be either marked "Damaged" (including random cosmetic damage or engine damage to the body) or simply be flagged Stolen. These can only occur while a Mechanic is on duty and they can respond to those. There can randomly be one car or a whole batch of cars included in this, and they can count towards Mechanic achievement progression. There could also be a new thing for this: NPC Police requesting a tow truck to bring away a criminal's car to either the gas station or the police impound. These cars are selected from vehicles that can be tuned at shops not TransFender, so like randomly tuned Elegy cars and what not. They randomly spawn at nearby shops and provide a "Modified car" bonus when taken away like the scrap machine does.
Often the ability to just search for a car to tow is something that's at the mercy of the server's activity at the time, most players are driving their own legally owned cars so the chance to actually hook up cars to the tow truck and bring them to the gas station is rare, and geeting a "Consecutive bonus" even more rare. When there are not a lot of people online at some given hour, Mechanics have *nothing* to do.
