LAS VEGAS –

Consumers who buy certified pre-owned vehicles are loyal to the automaker more than 62 percent of the time, according to a presentation from Experian Automotive at the NADA Convention and Expo here earlier this month.

Their manufacturer loyalty rating (62.2 percent) trails that of new-car buyers (64.8 percent) but is nearly three points higher than non-CPO used buyers (59.5 percent), Experian said.

Likewise, make loyalty is 54 percent for CPO, versus 47 percent for non-CPO used and 57.5 percent for new.

Certified commands 20.9 percent model loyalty, against 26.1 percent for new and 15.1 percent for non-CPO used, their data shows.

Listing price, mileage trends

In its Used Vehicle Market Report – Special Edition released in conjunction with the NADA event, Edmunds.com shared a couple other key differences that make CPO stand out: listing prices and average mileage on the cars.

For model-year 2015 vehicles, the average price on a CPO car was $24,941, with the non-CPO coming in at $23,884.  Average mileage on a CPO was 14,030, while average mileage on a non-CPO was 17,001.

Among cars from 2014, CPO units listed for $23,632, against $22,012 for non-certified. The mileage for certified vehicles averaged 25,725; for non-CPO, it was 29,175.

In the 2013 class, the average CPO price was $21,607, with the tag on a non-CPO at $19,817. The average CPO unit had 32,392 miles, versus 37,470 on a non-CPO.

Lastly, CPO vehicles in the 2012 model year had an average price of $19,967, compared to $18,563 for the non-certified variety. The miles were 38,499 on certified vehicles and 47,879 on non-CPO.
