Don't you have to buy one of these first, or do they come free with the vehicle?

Many of the higher end GM vehicles come with an On-Star device as standard equipment. You get emergency service free for a few months and then select what level of service you want thereafter. I just selected the basic emergency service - airbag alert, theft tracking, locked doors, etc.

I've never been in a high enough income class to know the answer to either part of your question.

On-Star is installed in many car models made in this country, but you have to pay for the service.
