FWIW Cadillacs website says financing offer and Costco offer is not eligible for V models.they're not at msrp. GM is giving $3k rebate on 4BW ('23 and '24) since November (and still so in Jan). You get another $1k off as a costco member. GM is also basically loaning free money at 0.9% interest for 36 month financing on 4BW as well. If you had the cash to buy it up front, you could generate $11k in interest over that time period.
so quite a lot they are offering, just doesnt show up on the dealer website unless you call and ask most of the time
