In a trailer for some other content or something like that, they had a billboard sign with a gas station and cars, so you know it is a possibility especially since it was on a survey. I doubt that they put anything on a survey that isn't possible to execute.
As for me, I would love to have a gas station/car lot/mechanic business on the largest lot available with toddler trykes & kid bikes in the in the showroom inside & scooters, ect. for kids. Mechanic skill/job would be a nice to have for home business or working in public. Since it would take a gamepack or EP, I would like junkers, bugs, bug van, classic cars, vans, drivable vacation home, large trailer to pull behind types for camping, normal cars, and then up to the high end ones. It is possible that this could be put in a S4 jobs EP. They could open up the ability to own apartments and expand on that. These could be sides like the photography & owning your own store was to the career EP we already have. They could add babysitting, house building job, stylist, home interior, and normal jobs like pizza place or grocery store. Since all of those have the main parts already in place, it would be easy to provide that as well as another profession or two. Maybe firefighter & burgler & open up the police station better. :)
I miss cars and the trolley or train opened up would be another nice addition for poor sims who can't afford cars. They could have signs like for fishing except they are railroad/trolley stops. :)
