OP, I don’t know about you but for anyone look at that artist’s other works in DeviantArt, I need to tell y’all; it’s “something obvious”. However, I’m only care and here for those cars because I recognize those; it’s from BeamNG.drive.
Speaking of BeamNG.drive, where did these SFM artists got those cars? I haven’t check SFM’s Steam Workshop page for a very long time, and I don’t recall there was a pack of cars from BeamNG.drive…
