It was a deal on TravelZoo, but you can probably find it on Groupon too. It was a good experience, but honestly I think you'd have more fun taking your own car on the track. I had more fun driving the Z. It's like $50 to do a 20-25 min hyperdrive session in your own car (on a bigger track) vs $150 to do 2 laps in the Lambo/Ferrari thing which is like 2.5 mins. If you still want to do it just to drive a Gallardo or F430 then go for it.
