After finding some pictures, the shape of the seat, whether clad in cloth or leather, appears to be identical, meaning I'm probably going to hate this car. Well, not hate the car per se, but hate the seat. It has side bolsters, sandwiching two panels. The upper panel covers most of the upper back, from the top of the shoulders to the end of the ribs. Then there is a groove between the two segments, which itself is a problem, before even getting to the lower segment. The lower segment covers from below the ribs to the bottom of the seat, and conceals the lumbar adjustment mechanism. This lumbar mechanism, even at fully flat, feels like it is active, although this may also be partially due to the feel of the groove between the panels.
I prefer a flatter single piece seat, something without lumbar at all. Unfortunately, this affects even luxury sport car. The G37 seat was not particularly comfortable to me, but it was better, because it uses three panels, with much shallower dividers between them, and the upper edge being at the shoulder blades.
