An experiment I did using various design cues from here and there. Not sure if the Synergy's spelling is correct but... :P
I have used previous gen Hyundai Sonata headlights and modified it a little, put the Pontiac Rageous style side signal lights, 04-08 Pontiac Grand Prix's vent below the grille, Oldsmobile Cutless Supreme's rear window quarter, 2000 Pontiac Bonneville's nose and changed it up a bit, along with the Mercedes Benz style, long flowing side lines. I also tried to depict the Asian/European makes' folding rear view mirrors, though it isn't easy to see. The rear tail-light is straight from Alfa Romeo 164 that I modified it a bit, along with 80's - 90's Pontiac's Fog Lights that sits in the bumper. The overall shape you will probably say, same old, same old 90's style, that's why I labelled it as Retro shaped P/U.
I hope you like it, though it's proportion have serious problems and there are bunch of errors here and there.
