With 10 sales days left in the month to move certified metal, Autotrader editors released their list of the best certified pre-owned offers available in March. For potential buyers looking to head into spring with the purchase of a like-new vehicle, the site said this could be the right time for dealers to help their customers upgrade the vehicle.

Autotrader executive editor Brian Moody reiterated the CPO sales pitch dealership personnel can relay to “ups” arriving at the showroom in person or virtually in the business development center.

“Certified pre-owned programs typically include an extended warranty and other incentives that provide long-term value, such as bumper-to-bumper coverage and exceptionally low interest rates,” Moody said. “These deals are the perfect option for a used-car shopper who wants the confidence of a new-car purchase."”

To assist dealerships and their customers, the editors at Autotrader highlighted the top monthly certified pre-owned deals, which include:

— Buick’s CPO program touts six years or 100,000 miles of powertrain coverage from the original sale date — a generous term. This month, Buick is also offering 1.9 percent interest for up to 36 months to qualified shoppers on three popular certified pre-owned models: the Enclave, Encore, and LaCrosse.

— Chevrolet’s CPO program offers an additional year of bumper-to-bumper warranty coverage beyond the factory term, and touts six years or 100,000 miles of powertrain coverage from the original sale date. This month, it’s even more appealing, as Chevrolet is offering 1.9 percent interest for up to 36 months to qualified buyers on several popular certified pre-owned models: the Cruze, Equinox, Malibu, Silverado, and Traverse.

— Ford’s CPO program is impressive, as it offers an additional year of bumper-to-bumper warranty coverage, along with seven years or 100,000 miles of powertrain protection from the original sale date. Through the end of the month, Ford is offering 2.9 percent interest for up to 66 months on all of its certified pre-owned models to qualified shoppers — an impressively long term for used vehicles.

— GMC's CPO program boasts excellent warranty coverage: in addition to one extra year of bumper-to-bumper coverage, GMC's warranty offers six years or 100,000 miles of powertrain protection from the original sale date. This month, GMC is sweetening the pot even further with a special interest offer for qualified shoppers: 1.9 percent for up to 36 months on all Acadia, Sierra, and Terrain models.

— Infiniti's CPO program is clearly among the best in the industry, as it offers excellent coverage that can, in many cases, last for six years — with no mileage limit — from the vehicle’s original sale date. Not offering a mileage limit is truly impressive, and Infiniti makes things even more enticing in March with an excellent low-interest financing offer. That deal boasts 0.99 percent interest for up to 36 months on all certified pre-owned Infiniti models to qualified buyers.

— Land Rover's CPO program boasts coverage for up to seven years or 100,000 miles from the original sale date. In March, Land Rover makes things even more appealing with a low-interest offer for qualified shoppers. Although the offer varies from model to model, it boasts 1.9 percent interest for up to 60 months on most 2013-2015 models — and 0.9 percent interest over that term for the popular compact Range Rover Evoque to qualified shoppers.

— Toyota’s CPO program offers one year of bumper-to-bumper coverage, along with a powertrain warranty that covers vehicles for six years or 100,000 miles from the original sale date. This month, Toyota is sweetening that deal with several low-interest special offers — but the best deal is on the Prius. The hybrid model doesn't just get excellent fuel economy, but also touts interest rates from 1.9 percent for up to 60 months to qualified buyers — a new car deal with a new car warranty for a used car.

— Volvo’s CPO program touts bumper-to-bumper coverage for up to seven years or 100,000 miles from a car's original sale date — longer coverage than virtually every rival.  Volvo is offering a special finance rate in March. Through the end of the month, Volvo is touting 0.9 percent interest for up to 24 months on all certified pre-owned Volvo models to qualified buyers.
