The following is the review I posted on the M5 forum:
"I only had 15 minutes (passenger only) but all I can say is F*CK this thing is so damn quick (I drove a 997 GT2 several weeks back and I could not tell the difference up to the 112mph limiter on this car), completely seamless full throttle changes and the grip levels are unbelievable - if you commit to a bend and keep the power on you can either go round like on rails or in a huge controllable powerslide, dependent on how you set the suspension (I was shown this - kept me smiling for hours).
I was also shocked how comfortable the ride was - no Rolls Royce but very similar to my M5 which really surprised me. the wheels are huge (20") and the brake discs nearly as big!
I was also told by the Nissan driver that the car is deffo 480ps....at the WHEELS!! that's around 550 at the flywheel then!! That explains the scorching acceleration times then..
V spec - is coming but likely to be very small power increase as the transmission starts to have problems at 600 ps apparently (nb after market mappers), carbon fibre brakes and around 150kg less weight.
£77500 approx apparently.
Two hours drive round trip but i can say I was one of the first."
Was I inpressed? Put it this way, my order is still in!
