There is a maximum 5000 cars entered and all the 2004 entries filled up during the 2003 Hot August Nights (a first). I believe the entry year cutoff date is 1971 and older. All the major casino's have a "Show and Shine" in their parking lots. I only visited the Atlantis parking lot on the 2nd to last day. There were probably 100 really nice cars at Atlantis, and a couple of them were rough around the edges. Some of the bigger casino's probably have close to 1000 cars in their lots. Nothing like seeing a 69 Judge next to a, 68 GT500 Shelby, next to a Hemi Cuda, next to Daytona Superbird and the list goes on and on.
