Hi Joe!
I assume you're talking about the upcoming "Ferraris & Maseratis on 12th" event?
It doesn't cost anything to show, just show up at the Ferrari dealer on 12th Ave in Seattle (preferably before the 10am opening time) on Sunday the 22nd. It runs until noon and after that, everybody will head down to Innovations in Audio in Bellevue for lunch. This is all I know about the event, if you need more info, contact them directly...
