Not sure about any in particular considering it's been about 7 years since I've lived in that area, but a great cruise spot that used to be a fun thing was on Sat night going to Scottsdale Pavilions at 9175 E Indian Bend Rd. Free where a bunch of people just show up and hang out with their muscle cars, street rods, custom mods, etc... There was a radio station there to play some music. Not sure if it's still around, but it's worth a shot.
Pretty sure that the Pavilions show is still going on. The Barret Jackson is coming up so there are usually other auctions before or after the B.J. auction. Scottsdale chamber of commerce should be able to tell you.
