Right, now I see where you're going. That's fair comment.
HOWEVER (and you knew this was coming...!)
Much like the 350Z, I could forgive the weight easily IF the quality of the interior justified it. IMHO, it doesn't. That's the exact same thing I've levelled at the Evora as well, so it's not just Nissan that have a monopoly on cheap interiors. Is the GTR interior acceptable? Yeah, it is, and at £60K it definitely was. Is the quality of the interior justifed by the extra weight it adds? I don't think so, but then there's other cars to level that at as well. Add to the fact that the price is now £80K and you're into a whole new argument.
