Just ask man, XM is always willing to bargain, tell them you have multiple vehicles and what to try XM for a few months on 1, say you are only willing to pay $70/year (that's the lowest I've heard of unless someone already has 3+ receivers).

 

Good show, but House all the way baby!!! Porterhouse on Area is the shiznit. I let XM expire because their house channels basically blew.
