Mind if I add a few crits? There are a few areas where the model is not accurate for instance like on the bonnet, the air intakes are slightly off. The headlights have no covers, there aren't any door handles. But they are minor things.
The only think I would work on is your mesh flow, you have quite a lot of triangles and your reflections are suffering because of that. Tweak these and you render will be a million times better.
Other than that though, your model looks nice and the render is pretty good too!
