Jaguar topped the J.D. Power and Associates Sales Satisfaction Index for the second straight year.
The study measures the satisfaction new-vehicle buyers express with the sales process.
In the 2005 study released Wednesday, Jaguar tallied 889 points on a 1,000-point scale. Lexus was second with 888 points. Last year, Jaguar and Lexus tied for first.
Buick and Porsche tied for third in this year's study with 878 points. Cadillac (874), Lincoln and Mercedes-Benz (873 points apiece) followed. The industry average was 842 points.
The survey found that the availability of new vehicles with the features that buyers want and the length of time customers must spend in dealerships are critical to consumer satisfaction levels.
"Dissatisfaction with the amount of time spent on the sales process is mostly attributed to the negotiation process," said Steve Witten, executive director of automotive retail at J.D. Power.
"Buyers typically talk to several dealership personnel before finally driving off the lot with their new vehicle," Witten said in a statement.
Among the 37 brands surveyed, Chevrolet finished 15th with 856 points. Ford was 22nd with 843 points, and Toyota was 29th with 824 points.
Isuzu was the lowest-ranked brand with 743 points.
Power based the study on responses from 37,296 new-vehicle purchasers in May. After the Big 3 launched employee-discount promotions in June, Power says, customer satisfaction levels with the price of vehicles increased.
