I think the diff between GT and T is too high - $44k. It's hard to really know since Lucid hides what differences exist outside of the simple configuration on their website. Looking at other manufacturers, the differences could cost somewhere around:
2 battery modules: $6k (Ford charges $6k to go from 70 to 91 KWh)
More powerful motor: Is this simply software controlled or is there a material difference? I'll be generous and say $3k
Surreal Sound: $7k (MB/Porsche upcharge for Premium Burmeister surround sound)
DD Pro: This is tough to value because Lucid has stated they are only going to provide L3 so it will be on par with Ford/GM/Hyundai systems. I'll put them between those and Tesla: $8k
Glass Canopy: $3k (Tesla MX windshield replacement is $1.5k). We should subtract cost of standard windshield but don't know cost.
Nappa leather + Alcantara vs Premium leather no Alcantara: $5k (Porsche)
Massage function: $1.5k (Porsche)
This adds up to $33.5k. Where's the other $10.5k in upgrades over the T? Based on the cost of the MX windshield, I'll be very disappointed if the T option for the glass canopy is much higher than $3k. Based on what other manufacturers are charging, a fully optioned T will be 95 + 18 = $113. Of course, we are comparing Tesla volume price from manufacturer vs small volume price for Lucid so the glass canopy could be double what I'm guessing and I already doubled the MX replacement cost. This would be true of all the items I've listed even though replacement cost is always higher than the cost included in the finished vehicle.
I think once the 3rd model comes out, they will raise the prices of all trim levels. Lucid will need to price differentiate between the top trim of the 3rd model and bottom of the Air. Inflation and supply issues will also figure into price increases.
