After I bought my (used) car, a free trial for Sirius XM was included. While it was interesting to play around with, the sound quality absolutely sucks, and without discounts its about $20/month.
I began getting sales calls on my cell phone (which the dealer obtained when I bought the car) . Well OK -- it was three calls. But each time I had to just say no and hang up. They do not stop at no.
I'm glad they do not have my credit card info because they seem unscrupulous. One of the calls offered my 5 extra months for $25, but then it would auto renew at the listed price, and I would not trust them with my credit card info.
I would recommend that anyone considering signing up for Sirius XM should do some careful due diligence first.
