Wow. I have to agree with Kolesky. The first thing that came to mind was the Astra Coupe. That's not a bad thing though because it looks really good and your chop does too. I love down to earth concepts like you've made here.
Yes, It's toony but It's really not that bad. You should focus more on the door lines because they look fake. I used to make door lines like that as well but you want the black layer to be at almost 100% opacity and usually the white layer on 5 - 10%. It's the white layer that makes it look so fake. It also looks like you left out the front of the car where you should have carried on the white highlight/reflection you have down the side of the car.
Keep it up!
