If you’re a dealer looking to move your CPO inventory, take note: Autotrader has come out with its top picks for certified pre-owned deals in September.

 “Certified pre-owned vehicles used to be kind of a secret, something only your uncle Ned and car guy neighbor knew about. Today, many people are catching on that it's basically a way to get a like-new car at a less-than-new car price,” said Brian Moody, executive editor at Autotrader. 

“A quick check of Autotrader’s monthly CPO deals shows you can also get other new car perks like low financing rates,” he continued. “Some perks go beyond just favorable APR: Cadillac is offering a year of free OnStar and Kia's CPO program essentially reinstates their excellent 100,000-mile warranty, something you can't get if you buy a used Kia from a private party.

“Plus, all automaker certified cars come with peace of mind, knowing the manufacturer of the car stands behind it with a factory warranty and authorized inspection.”

Autotrader Editors' Top Picks for Certified Pre-Owned Deals for September  

— Acura is offering a new-car financing rate for used vehicles: 0.9 percent interest for up to 36 months on certified pre-owned ILX, TL, and TLX models for qualified buyers. Plus, buyers get an additional year or 12,000 miles of bumper-to-bumper coverage beyond the original warranty.

— Qualified buyers interested in a certified pre-owned Audi can get 1.9 percent interest for up to 60 months on 2013-2015 Audi models. Plus, all cars in Audi's CPO program feature six years or 100,000 miles of bumper-to-bumper coverage from the original sale date.

— Cadillac shoppers can get 0 percent financing for up to 60 months and 12 months of OnStar service at no charge.

— GMC is offering 1.9 percent interest for up to 60 months for qualified buyers on its certified pre-owned Acadia and Terrain models. That’s a great deal for a used SUV — especially for one that includes GMC's lengthy, manufacturer-backed CPO warranty.
