Vehicles are common. Operational ones, not very. People to make non-operational vehicles operational, even less so. Basically if it's not a PMC vehicle, or an armored Mad Max type of rig, it gets destroyed by raiders if you leave the safe zones. The Peacers have their own motor pool of lightly armored stuff, though they're kind of unreliable.mechanically speaking. I figure at some point we can get our own (be it communal or personal) vehicle and start armoring/arming them/it. Smithing is kind of a revived art now, so finding someone to fabricate armor pieces is easy. It's just finding a trustworthy, knowledgeable auto mechanic that's difficult.

With that said, PMC/Government engineer types charge a lot to work on personal vehicles. I can't realistically see someone coming in with a mechanic character who is above average, seeing as 40+ years hiding from the undead made things like that almost a lost art. Everything learned would have to be mostly by word of mouth.
