I travelled down from Glasgow to Birmingham for the show last saturday, and I have some near exact same photographs as you that it is scary! I was bored with the actual car show after an hour or so, as it was that busy I couldn't get near half the cars. The top gear show was pretty entertaining though.
I sat in both 370z's that were parked outside, and I honestly think that the interior in the 350z is much nicer than the new one?
I also left the responsibility to my girlfriend to remember what car park we were in as I was on the phone when I parked my car up. Needless to say she was "sure" that it was N6.
Turned N6 carpark upside down, and my car was no where to be seen. She then said she was sure it was "N6 or N7".. After roughly 90 minutes I eventually found my car in N1
I was amazed at some of the exotic cars parked in the public car parks. I seen countless Audi R8's, GTR's, Aston's, Ferarris, Porsches etc all sitting outside as I looked for my car.
