There are a couple of things the unit could do with a facelift. I think i'd be a good idea to give it dynamic exhaust effects, a higher resolution floor texture and fix the footstep sounds, openable windows and checking the driver's break leaver 3D model as it looks like something should not be there but i'm not sure.
Thank you very much for that reference! in saying that the suggestion now goes to add the missing labels on the metal as seen in the reference
