Really like this chop! Saw another entry for the comp in another thread, But I think this has that beat.
If we start with the design of the car I like it a lot, it has a really low and slick look. It defenntly looks better with the top down then up, which makes it suffer from the same issues as the new Z4 (according to Jeremy Clarksson anyways). I can expect a few people reacting as if this doesn't look as a typical contemporal Nissan design, especially if you look at the 350Z, 370Z and the GTR. But I think this might actually be the way Nissan can take for 2013, since this would bring them back to their older models such as the 300ZX, but also even further back as the 280Z Fairlady which was a model even back when Nissan was Datsun. Also like the interior modifications that clearly indicate a larger, possibly turbo or supercharged, engine. The only thing I don't quite agree on is the choice of rims and the size of them. They look a bit to big for the wheelarches, if this was a concept there would be more clearence. But other then that it's great.
If we move over to quality I have little to say actually. Everything looks really good. The only thing that I think could have been improved are the doorlines and other, which look a bit tooney. Also there are some smaller pieces there on the FB that look a bit toony, but other then that it's great!
Nice concept, and really hope Nissan come to the same conclusion

Cheers!
