I know for my truck it was about $1200 for 4 more years, but you didn't buy it until the factory warranty was 2 or 3 months from ending. So, if they are like the rest of GM, you have plenty of time to save up for it.
i asked when i put down my deposit for the SKY and they said 1720 for 48 months/48000 miles car care plan. i asked saturday again and they said same prices as for the ion. i don't know what that is, but basically not adding anyp premium to it over the ion.
I got the CCP with my VUE and really loved it. Something about taking it in every 3000m, having them do everything and then washing it, topping off fluids, and not paying for any of it at that time appeals to me. I know, you pay for it up front...but I still like it!
