It's a bit uneven here & there but it does look good tho... I'd suggest you turn on Auto Smooth in the tab right after Modifiers
I've got a rough shape for the back end modeled out, right now I'm working on getting a basic jbeam to load into beamng for testing purposes. I have been putting a bit more time into my map that I'm working on currently though so sorry about that.
even though this is a European car and I'm making a map based of a location in the usa, The map is pine hills 2, I think i'll make a update for both today.
I may have made the model a bit to big This jbeam is really low quality and needs a lot of work but its a start considering this is my first vehicle mod. I plan on fixing up the jbeam and then finishing up the model, the final step will be texturing it all.
