Very decent job on the overall body of the car.. The concept is nice, and it was not as bulky as the old one. Overall from a distance, it looked nice. I would love if you take my suggestion and improve on the following possible errors.
For this image below, there is an indent sort of deal above each tail light. The tail light itself is not parallel to the actual rear body. I would like to suggest that you make this one somewhat flat area.

This area on both sides has an odd smooth shading error in an unnecessary location. The wheel arch should also either be large, or the wheel should be smaller. I prefer a mix of both.

The mirror has completely random positions for vertices and are not even or make a noticeable pattern. The gray mesh has a rather odd face placement as well.

The rear windshield passes through the side windshields.

You can technically see through this area between the front and side windshields. They should also not connect.

The back side of an interior usually doesn't contain the metallic/plastic exterior cover. I suggest making that part possible a black25-type deal. The top corners of the seats could also be fixed as the triangles are not symmetrical.

It would be nice if the side windshield was parallel to the roof area.

I suggest that the flat shading should continue in the pattern on the right side (rear corners).

This shading error should be corrected.

There is an opening cut in front of the wheel arches. I'm uncertain whether it repeats itself onto the right side.

There may or may not be other errors that I did not notice. I enjoy the look of the body, but I ask that you should fix these specific areas and improve on your design a bit. Touching models up is always a good thing, and you show that you like to improve. It is still a rather stunning model.
Keep up the good work!
