If you’re trying to maximize incentives, you’re at the mercy of vehicle eligibility. The biggest limiter is probably Studio Select, which seems to be limited to select on-site inventory. There’s no good way to know what vehicles are eligible without calling and asking. To my knowledge it seems like the Gravity Touring and certain Air trims are the most frequently eligible. Otherwise, it appears Conquest is now also limited to on-site inventory but without the extra requirement Studio Select has.
As far as missing options - are you talking about in regards to certain models being excluded from certain incentives (as above) or something else? For the 2026 gravity inventory near me, I’m able to see leather interior for both 5 and 7 seaters.
Lucid’s rate estimator isn’t perfect and doesn’t include selectable options for all the available incentives, presumably because some are either unadvertised or change so frequently or are vehicle-specific. The workaround is to manually input the incentive value into the down payment section (and mentally exclude this down payment from the due at signing value). Alternatively you can ask your sales associate to send you a quote and they can also guide you on what vehicles are eligible for what incentives.
To lease a $125k GGT for 36mo/10k miles, the configurator gives me anywhere between $1350/mo (conquest, studio select, trade in, and employee) to $1580/mo (conquest and employee) depending on which incentives you put in.
