While I love seeing burnouts and well modded cars (and I'll admit the occasional breast is pleasing to the eye) Summernats has devolved over the last few years to being the last place you'd ever want to take any of your family to look at cars.
Any vague semblance of tolerable behavior is straight out the window. It'd lowest common denominator central in there!
Oh and I'm sorry but a Holden Gemini painted metallic purple with 24 inch chrome wheels and 10 profile tyres is not a street machine, it's a wank.
That said, a couple of years ago I was there on the friday for the burnout comp when the Jack Daniels top fuel funnycar that they've built expressly not to have traction was smoking it up and OMG, I've never felt anything so awesome in my life.
I'm conflicted, stunning cars are great to look at/watch but anything winning nowadays has usually just had some rich dude walk into a rod shop, throw 200k on the counter and said "Build me a car that will win top elite at Summernats." They're largely not cars being built by passionate car enthuiasts themselves.
And the troglodyte behaviour is unacceptable, Summernats or not.
