(December 11, 2009) Resale value and vehicle quality have become increasingly important reasons for new-vehicle buyers to remain loyal to an automotive brand, according to the J.D. Power and Associates 2009 Customer Retention Study.

Now in its seventh year, the study measures the percentage of vehicle owners and lessees who replace a previously purchased new vehicle with another from the same brand. Retaining existing owners is critical to a brand's market success, particularly in the current challenging market conditions.

Mercedes-Benz ranks highest among automotive brands in retaining vehicle owners when they buy a new-vehicle, and improves their retention rate by eight percentage points from 2008 to 67 percent in 2009. Following in the rankings are Honda (64%) and Toyota (61%).

"Mercedes-Benz has steadily improved its customer retention rates during the past five years, and in 2009, has achieved the highest rate ever attained by a manufacturer since the inception of the study," said Festekjian. "In particular, customers cite the resale value and appearance and styling of Mercedes-Benz models as primary reasons to remain loyal to the brand."

Overall customer retention in 2009 has remained stable from 2008 at 48 percent. In 2009, 13 of the 36 ranked brands have improved in customer retention rates from 2008, while 20 have declined and three have remained stable. MINI and Porsche posted the greatest improvements in customer retention rates from 2008, each improving by 14 percentage points in 2009. For MINI, this improvement is driven primarily by incentives and customer perceptions of resale value of the brand's models. For Porsche, the increase is due to resale value, fuel economy and quality.
