The existence of discrimination by the sellers of second-hand cars is a little studied subject, whereas the possibility of acquiring a car conditions multiple aspects of economic and social life. In this article, we apply the correspondence test method to the purchase of a used car in order to measure the extent of discrimination in this market according to the ethnic origin, gender, place of residence and age of the applicant. We constructed six profiles of fictitious individuals, perfectly similar except for their age, gender, origin indicated by the consonance of their surname and first name or place of residence. Between January and May 2015, we used these fictitious profiles to respond to 489 used car sales ads located in Ile-de- France. Statistical analysis of the responses to these tests reveals the existence of discrimination according to gender and place of residence. The analysis shows that information based discrimination prevails on the second-hand car market rather than taste based discriminations.

二手车销售商是否存在歧视是一个很少研究的课题，而购置汽车的可能性则限制了经济和社会生活的多个方面。在本文中，我们将对应性测试方法应用于二手车的购买，以便根据申请人的族裔，性别，居住地和年龄来衡量该市场中的歧视程度。我们构建了六种虚构的个人资料，除了年龄，性别，出身（由姓氏和姓氏或居住地的谐音指示）外，它们完全相似。在2015年1月至2015年5月之间，我们使用了这些虚构的资料来响应位于法兰西岛的489辆二手车销售广告。对这些测试的回应进行统计分析，发现存在根据性别和居住地的歧视。分析表明，基于信息的歧视普遍存在于二手车市场，而不是基于口味的歧视。
