My vote is for the top rendering. Keep the polished outer hoops and semi-gloss black the centers, and keep all the trim shinny. Why isn't there a back bumper?
For the record I do like the 3rd rendering a lot! I just feel that the car needs consistancy and that if you are going to black out the exterior wheels and trim...then the under hood and interior needs it too. And that 3rd one screams cage and race style seats like in the rendering!
But at the end of the day...this is only my opinion!
