Main Point: THEY TAKE WALKINS!!! It is not on their website but they let you just walk up, register, and drive!
Was there yesterday and it was fantastic! Basically you show them your open license and they take your detils to let you in their new model to drive on a really expensive urban track they somehow got up there on the roof. it's through a (secret?) Yellow door.(AKA: Golden Square Car Park on Lonsdale Melbourne)
It's really fun!!! If you're nervous,don't worry, they put professional drivers with you to make sure you know what you're doing.
Wouldn't this be better suited to the forums? I don't this is classed as a deal.
