Consumers purchasing a used car, equipped with satellite radio, through leading auto dealer Sonic Automotive, will now automatically receive a three month trial Sirius XM subscription.

This deal with Sonic Automotive puts SiriusXM in front of potential customers in over 100 dealerships across 15 states and 26 major metropolitan markets.

After the recent similar partnerships with AutoNation and Asbury, SiriusXM now has their three month deal in over 500 new dealerships since the beginning of 2012. 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.

Sonic Automotive, is a Fortune 500 company and among the largest automotive retailers in the United States.

"Sonic dealers are devoted to giving their customers an attractive selection of pre-owned vehicles," said Harold McLarty, Vice President of Pre-Owned Vehicles, Sonic Automotive.  "SiriusXM is installed in many of the pre-owned vehicles we sell.  So, delivering 3 months of SiriusXM's expansive programming is a value-added feature we are excited to provide our customers."
