Two GM brands best all others in JD Power Customer Service Index (CSI) survey

Cadillac is on quite a roll.

Cadillac has enjoyed massive growth in the past few years. The Cadillac ATS Coupe, pictured, looks to continue that success when it arrives later this year.

With the first-ever ATS still making waves
, a brand new CTS
just hitting dealerships, and the yet-to-be-released Cadillac Escalade only a few months away, it’s no wonder the company has seen some of its hottest months on record.

Best of all, Cadillac customers also leave the dealership with the most positive experiences
, according to JD Power.

The annual study measures how satisfied customers are based on the customers’ experiences with the dealership.

The study examined 90,000 owners and lessees’ of 2009-2013 model year cars and how satisfied they were with their dealership service.

Cadillac out-flanked Audi and even Lexus, last years’ winner, to take the crown in the luxury segment, while Buick beat both MINI and Volkswagen to take the crown in the mass-market segment.

The study was fielded between October and December 2013. J.D. Power measures dealer service in various countries around the world, including Australia, Brazil, China, Germany, India, Indonesia, Japan, Malaysia, Mexico, the Philippines, Taiwan, Thailand and Vietnam.
