These cars are "art" more than anything else. Go into it with the expectation that they were built to be eye candy and nothing else, and you should enjoy it. These guys are just as passionate as we are about our cars, and that's a good thing.
But if you walk through and think to yourself "Holy crap! Look at the control arms and how messed up the geometry is! That's way too much camber! Why stretch your tires?"... you won't have fun.
These are modern expensive rat rods, but more in common with the BMW Art Cars than anything else.
You'll see beautiful engine bays, blingy wheels, and the like, but there will be a lot of stuff done with incredible attention to detail.
I like these shows. I wouldn't personally own most of the cars, but eye porn is eye porn.
