Saw a few cars. Naming some that I can remember:
McLaren P1 GTR, 2x 650S, 2x 12C
Lamborghini Huracan
Tesla P90D, 2x P85D
Ferrari California's & California T's, many F430s, 5x 458, 2x FF, F12, 328 GTO, 308, 550, 348, 250 & Enzo.
Some other Porsches in there including a 911 GT3 RS & Cayman GT4.
Great day.
I also spent some time at KPMG Manchester but not sure if that lives up to some of the cars I saw today.
