Just weeks before the holiday season approaches, Autotrader has come out with its top picks for certified pre-owned deals in October. 

That list includes attractive incentives from BMW, such as comprehensive coverage with no mileage limit at the end of the original four-year/50,000-mile warranty that's included on all new BMW models.

"One advantage for shoppers today is that certified pre-owned cars and trucks are lightly used, and they have a long factory-backed warranty for greater peace of mind over a typical used car," Autotrader executive editor Brian Moody said in a news release.

"We also saw more manufacturers provide a couple of options on CPO deals to give customers even more flexibility when it comes to saving on pre-owned vehicles."

Audi's CPO program offers comprehensive protection for up to six years or 100,000 miles from the original sale date. And through the end of the month can get 0.9-percent interest for up to 24 months on all CPO Audi 2014-2016 models.

For October, BMW's CPO program is now touting one year of comprehensive coverage with no mileage limit at the conclusion of the original four-year or 50,000-mile warranty.

Shoppers can also opt to purchase additional years of coverage. Additionally, a new special offer also gives qualified shoppers 0.9-percent interest for up to 24 months on all certified pre-owned 2014 and 2015 BMW models.

Throughout the month, Chevrolet's CPO program offers both powertrain coverage for up to six years or 100,000 miles from the original sale date and bumper-to-bumper coverage for one year or 12,000 miles from the original sale date

This month, GMC is also offering two warranties. Its program currently boasts six years or 100,000 miles of powertrain protection from the original sale date, and bumper-to-bumper coverage for up to one year or 12,000 miles from the original sale date.

Honda's CPO program features a warranty that covers Honda models for up to seven years or 100,000 miles from the original sale date and a bumper-to-bumper warranty for one year or 12,000 miles of coverage from the date of purchase.

Throughout October, Mercedes-Benz is offering one year of coverage, which drivers can extend to up to three years of unlimited-mile protection for a fee. And qualified shoppers interested in a CPO C-Class can get a 3.49-percent interest loan for up to 36 months on all CPO 2014-2016 C-Class models.

Nissan touts two incentives this month. The program is currently offering 1.95-percent interest on all CPO models for up to 36 months, or 3.99-percent for up to 72 months. This month, some shoppers can also get cash back for their next CPO purchase. Nissan’s CPO program is offering up to $450 cash back on certain models.
