I also went to the show, for $20 it was disappointing, Adelaide has not really put on a good motor show at wayville for years now, yes there were some nice cars and some good old classics there, but then it was ruined by having dealers fill gaps with today's tin cans, after hearing a lot of comments most petrol heads were there looking to admire some old school quality.
At least there was the Zippel run, not that i was there for that, but i have seen the cars in the past, in fact it would be worth paying the $20 bucks to see them and forget the wayville show grounds, all you do is pay parking fees.
On the other hand the show was well organised and well set out, as usual the food was expensive and there was a lack of hot foods, and surely in 2013 these outlets would cater for credit cards but no all food had to be cash, you can understand why people bring sandwiches and flasks.
