Very nice work. All it needs is for the polygons to be "detached" so the black shadows across the model will be cleaned up.
To the other modders watching, please take note. Pay attention to how the edges flow forward along the body and curve until it stops at the front. The roof, like on 99% of cars has a flat roof, the hood is where it gets tricky. Modern cars have that hood which starts along the side and then transitions forward into the hood.
The little lip at the bottom of the bumper is also something thats not easy to pull off, but it can be done by adding enough rows so it connects at the bumper and grill, as you can see in alexCNP's model wireframe.
