Since you're focused on engines, maintenance and repair -- probably not, but I'd like to clarify.
I'd like to post a photo of a car, I spotted and ask, what kind of vehicle is this (manufacturer model, maybe get some tech specs).
I might try to foul you, that I'm trying to identify this car, because I need to buy a spare parts for its engine. :> But, no one is going to believe me, right? :>
