Deal Check: Hummer EV SUV Omega (repost)

Sorry for posting again…felt like this got buried so wanted clearer visibility.

2024 Hummer EV SUV Omega: MSRP $140,645

36 month, 12k miles. $873/month. $1000 down
$2500 check back to me. GM pays first month

Ok. Here is the deal sheet at this point. This is pretty confusing to me so maybe someone can advise.

The advertised selling price pre-incentives was $102,999.

Then I qualify for Costco, Supplier and GM card, which is $3750. I have to put $1k down for the GM card one. The cap cost reduction includes a $3000 retired loaner and the $1000 I would put down

In order to fund the deal, they have to give me a check for $2500 back. It feels like I’m losing out on a few grand just to get the adjusted cap cost above residual?

Can someone tell me if something’s off here?

No need for duplicate threads.
