Welcome.
I’m doing this from memory because the programs are still fresh in my head, but please verify everything in this post.
I’m using 1, 2 and 3 for shorthand; I know they revised the trim names for 26, and I’m only commenting on AWD.
Lux 1 has the best RV and MF
Sport 1 has the same RV, higher MF
Lux 2 and Sport 2 lose 2% on the RV, so you’ll see a big cost jump relative to the MSRP delta. I believe the MFs are also higher on both.
L3 and S3 are horrible from a value perspective.
Incentives depend on what you qualify for and where you’re located. You can look them up in Rate Findr if you become a Super Supporter.
The most significant discounts are going to be on loaners.
Below is a link to a post with seven example deals from Feb just to give you an idea. Most or all of these have Costco (1250) and Retired Service loaner (1k). They’re both gone. Some regions I believe have replaced the 1k with something else for March.
And Cadillac just added a $500 private offer that you have to get for yourself to apply to any deal you put together.
New GM Rewards card ($500) I believe is also national, as is Conquest (which I think is still 2k). EV Supplier should be another $1k if you qualify.
