IRVINE, Calif. -

Kia Motors America said that last month's certified pre-owned sales marked its best April ever and more than a 5-perecent increase. And this, right after Kia had its best first quarter ever for CPO

Last month, Kia sold a 6,953 vehicles, which was up 5.6 percent year-over-year.  CPO sales have risen 14 percent year-to-date, reaching 26,406 units, according to Autodata Corp.'s April CPO retail sales report.

"Kia's record CPO sales are not surprising when you consider Kia offers the longest powertrain coverage, excellent financing incentives and a strong inspection process," IntelliChoice director of data products Eric Anderson said in a news release. "This is why IntelliChoice awarded Kia the best popular brand CPO program."

Kia’s CPO program only accepts Kia vehicles that are five years old or newer with less than 60,000 miles, according to KMA. Each vehicle also undergoes a 150-point quality assurance inspection by certified technicians.

Additionally, KMA said all Kia CPO purchases come with a 10-year/100,000-mile powertrain limited warranty and 12-month/12,000 mile Platinum Coverage.
