Seems like a good price to me. Would cost over 20k to import something simular + compliance.
Front lip and watanabes would set it off. Front lips are easy to get hold of through yahoo auctions- http://auctions.search.yahoo.co.jp/search?p=gc10&auccat=26322&aq=-1&oq=&ei=UTF-8&slider=0&tab_ex=commerce
And there are numerous local suppliers selling new watanabes at reasonable prices.
