General Motors has launched its Factory Pre-Owned Collection portal to offer used Chevrolet, Buick, GMC, and Cadillac vehicles to online buyers.

The automaker is the first to open up its remarketing channel to consumers through an online portal, which will take advantage of the OEM's Shop Click Drive car-buying service. The site will contain more than 30,000 used cars with less than 37,000 miles on the odometer, including company-owned, off-lease and daily rental vehicles. 

Buyers have online access to over 40,000 GM vehicles, which have fewer than 37,000 miles. They include an extended factory bumper-to-bumper limited warranty.

The service offers features such as a three-day or 150-mile exchange program, a three-month trial of the OnStar Guidance Plan and the Sirius/XM Satellite Radio all-access package and more. Vehicles will also come with roadside assistance and courtesy transportation during the warranty period.
