Abstract: 본 발명은 온라인(on-line) 상에서 중고차 매매상, 법인 및 개인이 보유(매입)한 자동차를 공매 방식을 통하여 매매할 수 있도록 하고,매매를 위한 중간 유통 단계인 평가,정비,탁송 등의 전 과정을 상기 중고차 거래자들이 직접적으로 관여하여 선택 처리할 수 있도록 하는 중고 자동차 원스톱(ONE-STOP) 매매시스템이다. 
     현재 중고 자동차 매매방법에는 매매상사 및 경매장에 의한 거래 방법,직거래 방법이   있다. 매매상사를 통한 유통방법은 자동차의 상품화 및 '자동차성능점검'을 통한 거래의 보증이 가능 하다는 장점은 있으나,유통단계가 불투명하여 매입시와 매도시 자동차의 이력 및 상태가 상이할 수 있고,이를 정확히 파악할 수 없으며 유통과정상의 비용이 판매가의 10~20% 정도로 과중하여 판매자와 구매자의 손실이 크다는 단점이 있다.경매장을 통한 유통방법은 다른 방법에 비하여 높은 가격에 매각할 수 있는 장점은 있으나 자동차를 일정한 장소에 집결시키고 정해진 날짜에 실시하므로 판매시까지의 소요되는 기간이 장기간이며 구매자가 매매상사로 제한되어 있어 결국 중고 자동차 유통단계를 한 단계 증가시켜 유통비용이 증가 된다는 단점이 있다. 또 직거래 방법의 매매는 유통마진이 없다는 장점은 있으나 다른 매매방법과 마찬가지로 거래 자동차의 정보가 불분명하고 구매자의 경우 거래에 대한 보증이 불가능하다는 단점이 있다. 
     본 발명은 이러한 단점들을 극복하고 장점만을 취하기 위하여 중고차 거래자 및 자동차 평가 업체,정비 업체,탁송 업체들 간의 네트워크 구성을 통하여 판매자 및 구 매자가 직거래 및 공매를 통한 매매방법을 선택할 수 있도록 한다.자동차 상태에 대한 진단 및 평가는 전문가 집단에 의하여 객관성 있게 실시함으로써 자동차 평가에 대한 보증을 제공하여 평가에 대한 신뢰성을 높여 자동차 진단 평가를 활성화할 수  있도록 한다.또한 상품화 과정을 판매자 및 구매자가 직접 진행하고 이에 대한 정보를 확인할 수 있어 자동차 상태에 대한 정보를 투명화하며, 정비업체에 일원화되어있던 자동차 진단과 수리를 이원화하여 불필요한 수리를 줄여 자동차 수리를 투명화함으로써 고객(판매자, 구매자)의 이익을 보호할 수 있도록 한다.또한 중고차 거래자의 탁송 의뢰시에 탁송 업무를 진행하며 탁송시 인도된 자동차와 구매자가 확인진행한 자동차가 상이한 경우 자동차 하자에 대하여 일괄 처리한다.상기와 같이 본 발명은 중고 자동차 공매 중개 서버 관리자의 관리 책임 아래 매매 당사자인 판매자 및 구매자가 직접적으로 매매 성사시까지의 모든 거래과정에 개입하여 평가, 정비, 탁송까지의 모든 업무처리를 선택 진행하는 중고 자동차 원스톱 매매 시스템이다.  
     이는 직거래 방식으로 유통마진을 제거하여 고객의 이익을 높이고 자동차 수리 및 중고 자동차 유통과정을 투명화하고 음성화되어 있던 중고 자동차 상품화 과정을 양성화함으로써 자동차 정비 시장 및 중고차 시장의 투명성과 산업화를 제고할 수 있다.
