Nice update. On last picture, there is two issues :
- Lower fold in front of the door : looks like there is unwelded vertices there.
- On rims : outer side of the 8 spokes are weird, like a vertice too far from the middle axis of each spoke. Especially visible on rear rim, the spoke going down and front, the bottom side of the spoke.
The car looks a LOT better now, But the wheels suffer in comparison now. For one your wheels are lopsided it seems or bent on all sides if we are talking real world comparison. I never really used the trick of sticking a wheel into a tire, I usually just modeled them all together at once, or if I did use two parts it was where the spokes where hidden inside the wheel tires. So in that respect I would have the outer rim and tire all be one part and the spokes be another. On the overall tire I would make it lower profile, they seem to really be squeezed under that chassis.
