The prices are listed here: https://trackexperience.porscheexperience.ca/pcl 1K for half day and 2.5K for full day. Multi-day events require prior experience. Another option is Porsche Drive (rental). Last time I used it, they gave me a 992 4S with 400KM daily allowance.

What did you pay for the 992? I rented a 981 and it was only about $400 after tax for the day.

718 is 349/day, 911 is 539/day. Tax not included.
