I never went myself. But my grandparents went a few times with their friends and enjoyed it. They all had/have old iron though. I'm not sure if there's a lot of newer stuff to check out.
I remember going a couple of times way back in 2005 or so and it is basically all of the worst of the import scene with a handful of good clean cars. It's probably changed and gotten better over the years but it was like going into a lame club full of mostly shitty cars.
