This looks quite nice. There's only a couple things I can find on the car, the first is some texture stretching or blurriness on the side, right at the front end, the bodyline that comes down around the headlight area looks like half of it tapers out larger towards the bottom.
There's also the interior carpet that's stretched in some areas, and much lower res than the other details.
There's a window lever in the back seat? I'm not familiar with the car enough to know if that's right or not
And I'm looking forward to seeing some pics of your mercury tracer
