Lexus, Buick and Cadillac dealers do the best job providing repair and maintenance services for their customers, according to the J.D. Power and Associates 2006 Customer Service Index Study.
Volkswagen and Isuzu owners are unhappy with their dealers, according to the survey.
Lexus is at the top of the survey with an overall score of 912 points on a 1,000-point scale. Lexus climbed from the fourth spot in last year's survey.
Buick comes in second with a score of 911, followed by Cadillac with 909.
Isuzu is at the bottom of the list with the worst score for the second year in a row with 781 points. Volkswagen with 810 points and Suzuki with 823 are not far behind.
The J.D. Power customer satisfaction survey is based on six areas of service: service initiation, service adviser, in-dealership experience, service delivery, service quality and user-friendly service.
The research firm collected responses from 79,580 owners and lessees of 2003-2005 model vehicles.
J.D. Power says a score gain of 10 points for satisfaction with the service adviser or in-dealership experience can add between $40 to more than $300 per customer annually, averaged over a one-to three-year customer base.
