Just signed up for the following on 5/6 @10:30am:
McLaren MP4-12C (7 laps)
Ferrari 458 Italia (7 laps)
The McLaren must've just pulled into their list yesterday or today as I was out there Sunday about to book and waited because I wasn't on a secured network. Glad I waited!!! Paid for the onboard video as well - will post it up when we get back, along with my review.
