haha dang that is a steal!! I'm not sure what shape yours was in when you picked it up but 350 bucks is hard to beat!
and the show is really rad, If you haven't then for sure check out jdmlegends.com, he restores classic japanese cars for a living right here in utah and they are awesome! But I'm pretty sure it's him that hold the event, its pretty small and not a lot of people know about it but it's getting bigger! theres a page called utah japanese classic cars on facebook ( https://www.facebook.com/groups/738108372880013/ ) and it usually gets posted in there before it happens. actually, I'm sure you've both seen Gord's 2009 240z build thread, he in insanely detailed and gifted in his craftsmanship. but second to last page this guy posts some pics of his car, almost at the bottom of the page. the red rb swap 240 post by "stony", that dude is a utah local and at least one of the pictures he posted was at tinners, in the spot he always is in haha.
