哈雷機車為美國百年經典品牌，享有高等的品牌溢價，也是全球在地化（Glocalization）操作成功的案例，本文從行銷3.0的趨勢形成的外在脈絡：協同行銷（collaborative marketing），文化行銷（cultural marketing）精神行銷（spiritual marketing）等三個構面，經過訪談、文獻映照、田野調查，呈現出台灣哈雷機車車隊的主旋律與變奏，主要研究結論顯示：1.哈雷百年經典品牌的主旋律（key themes）基調不變，卻隨著十年的文化，政治，經濟變遷，產生品牌的變奏（variations）：持久的迷人主旋律基調與美國自由騎士文化底蘊（哈雷機車的品牌四大構面），加上每個世代的配適性變奏，成就百年經典品牌。2.台灣哈雷騎士認同美國自由騎乘的夢想，在台灣哈雷機車雖為奢侈品，但這奢侈品卻不是炫耀財，也不是拿來提升社會地位，而是挑戰自我的騎士配備。3.全球品牌在地化轉型：台灣哈雷騎士間的社群文化不是美國孤狼文化，反而接地氣，成為重視友誼與親情的社群。
