I think you want to throw a couple of hundred more triangles at it, currently it looks a bit dated due to the polycount.
Shouldn't the wheel hub be inset from the tyre?
Also having internal detail on the windows looks a little odd too, and the engine detail being a flat texture again is a little strange.
Overall though, the shape and proportion is really good, the texture is well mapped apart from the front where it all looks squashed up vertically.
I found that my first couple of cars weren't too good, but the more you do the easier it becomes.
