While it's sad to hear about dealerships closing from a standpoint of people losing jobs and another business shuttering their doors, I can see the sense of it also. The closing of the small dealerships that sold less then new 1 car a week (or other small number) could result in some serious savings in the management of the supply chain, staff needed to support these dealers, marketing and other materials that get sent to dealers, and a ton of other ways to tighten the purse strings on their expenses.
I think the impact from the dealerships closing will be minimal if at all on SiriusXM. People that still want their Dodge or Chevy will still go to a dealer to get one, just instead of visiting the dealership 3 miles away, they may have to go a couple extra miles.
When I look at the local area around me, GM for example with the Chevy dealships is excessive, I have over 6 of them within a 15 minute drive from my house. If the the little guy down the street closes shop thats sad for him and his employees to be sure, but I would of bought mine at the lot across town anyways that has a bigger selection on site, with a decent sized in house staff for servicing, etc that the little guy could never afford.
