Literally in the same boat. I didn't want the moonroof, but got the ultimate for the seats, among some other reasons. I don't want to order a GM, but may consider a RAM...then when the KR comes in (assuming it doesn't get canceled), if the market remains unchanged, take delivery in order to flip it.
But $300 credit is laughable.. I hope they clear up if the dealer will install the module later, assuming the air blater seats aren't swapped for normal ones.
