I think it's both fair and obvious to say that Nissan should get some points for originally throwing down such a gauntlet, making Toyota and Honda stand to attention and have a benchmark to beat.
They were first out of the gate, and any time limit between when the R35 set the lap record, up until it was beaten by one of these manufacturers, will be hanging over their head for all time...
I do think Honda will go well in this one, I have always loved the NSXs... I remember seeing one when I was younger and nearly creamed my pre-pubescant self somehow!
The LFA, I dunno that much about it, but Toyota don't seem to be as head strong and competative as the others... But hopefully they will give it a big go
In the end, Nissan wants to beat Porsche, Honda wants to beat Nissan, and Toyota just want to win... It's quite an exciting time
