The average score of luxury auto manufacturers increased by two points, as Forrester ranked CX quality of 22 luxury and mass-market auto brands. For the third year in a row, top-notch purchase experience puts Subaru ahead of other mass-market counterparts. On the luxury side, Lexus is still No. 1 for service quality, and Mercedes-Benz remains the leader in purchase experience. Audi increased its score significantly and jumped two spots since 2017.
