Sirius XM has now added Penske Automotive to their growing list of pre-owned dealership partners.

Penske customers, like those at Autonation, Asbury, and Sonic, will score a three month free trial when they purchase any used car with a factory satellite radio receiver.

Penske Automotive Group (NYSE: PAG) is the second largest publicly traded automotive retailer in the united states (when measured by total revenue) and has 119 dealerships located across the United States.

“Penske has offered satellite radio on new vehicle sales through our dealerships since satellite radio’s earliest days,” said Rob Kurnick, President, Penske Automotive Group.  “By offering 3 months of SiriusXM programming in our pre-owned vehicles, we are delighted to introduce even more of our customers to an innovative service that will greatly enhance their in-vehicle entertainment experience.”

With the company seeing 30-35% of those exposed to this program converting to full fledged subscribers, this is more good news for SiriusXM investors.
