Is it a game model?
Even so I think you should work on it a bit more modeling wise, you don't have to model it in precise detail but the front of the car needs a bit more work.
It's the face of the car if you make a human(oid) game character you alway put in the details as well ( you don't take a sphere scale it in Y and cram a face texture on it do you?)
I have added a jpeg which hopefuly shows what I mean
