I got a couple friends to sign up for the event in Charlottesville, VA on 13 Nov. Sadly, it appears only the Z4 and M cars are available with a proper gearbox. I hope all the cars arent beige leather with light burl wood trim

From what I hear, the actual rules are kinda lax in terms of what car you can drive, right? If someone signs up for one or two, but has time to do more, are they permitted to do so given availability?
