First of all, it is free. Just sign up for a player's card at Caesar's or any other affiliated casinos and you will receive a free coupon for two people.
Second, the collection of cars are out of this world! Prior to seeing this collection, I was not a big fan of Ferrari. The collection here made me a believer. The sheer number and variety of classic Ferraris on display was incredible. There were also many classic Ford Mustangs (e.g., Shelby, Fastback, Shelby GT) on display. I am partial to classic Mustangs and they were all beautiful. I wish I had one. Sigh.
BTW, most of the cars on display are for sale. So if you have an extra $200K lying around, I recommend buying one of the Mustangs or Ferraris.
