Whew! Just finished CGmaster's car tutorial for Blender, what an awesome course. If you want to improve at hard surface, I highly recommend it. Because not every car is available on Sketchfab for free! https://cgmasters.net/training-courses/master-car-creation-in-blender/ Sorry I'm sounding like an ad but honestly it's worth it. Rigged with the free Rigacar addon. If you plan to animate this, then be sure to check out their documentation on Youtube. This car will feature as part of an upcoming BIG animation, so more to come. I'm planning on posting project files here so give me a follow if you're inclined. I'll continue to post free models as long as it remains fun :)
