I found this over on LS1tech and i gotta say, out of all the firebird concepts i have seen so far, this one's actually not half bad!

that's a cool lookin car, dunno about as a firebird but still cool. Looks like a G35 in the back.

Make the top even with the rest of the body and not narrow at the back or work the lines not so sharp to look like a 350z.

Like the headlights an front a bit, but the rest... not so much.

yeah i really only like the picture that's on the 2nd page, the one of the front view of the car. I do not like the back of it at all...

that thing is smokin hot. the front end could look great compared to good as it is right now, with some minor tweaks

i like the one that looks like a 77 better, but this aint half bad
