The explanation of the interior trim being that way in order to achieve weight savings. I hadn’t heard that one before. ( but I tucked it away for future selling persuasion purposes ).
The only rational explanation I could think of, regarding the grade of interior & seats: late in the development process there was an “oh sh1t” moment when it was discovered that costs had gone wayy to far out of control given all of the Cadillacy content items and electronics up the wazoo. So changes were made to interior materials and seat design so as to keep costs/price beneath the roof ?
