PS this what I believe is true. If I am wrong, my apologies - please correct this..
1. Unless a dealer changes the deal, GM charges:
2. $2200 at time of purchase for SuperCruise for the first three years of operation.
After 3 yrs, $25.00 per month
2200/36 = 61.00 per month, just for supercruise
3. also requires Onstar subscription
$9.99 to $34.99 per month (there are 4 levels of service).
.
so GM supercruise real monthly cost
A. during during the first three years can be: $71.00 to $96.00
B. after the 3 yrs, it can be $25.00 + ($9.99 to $34.99), or $45 To $70 per month
