I think Infiniti would be a difficult division to continue funding (for a cash strapped company like Nissan) as it doesn't have a global presence of any significance. At least brands like Buick and Lincoln have China to help generate some sales volume.
Ford's head honcho said many times that he's really concerned about them Chinese automakers. Should he pay more attention to the rise of Hyundai/Kia in the U.S. EV market?
My first car, waaaay back in 1981 was a 1970 Ford LTD formal roof 2 door sedan in dark green...fun for 3 months until the frame broke while I was trying to do a holeshot....lol. Lots of Northeast rust through the frame....replaced it with a 1969 LTD XL sports roof that was wrecked in the front end....took the entire front clip off my '70 and put the motor and trans in it using Dad's 1975 F250 Hi-Boy plow lift to pick the motor/trans up and drove it into place....19 year old ingenuity at it's finest....
Oh, I hadn't seen the order guide.
That tells me it's probably the same size hole in the roof, it just doesn't open. Probably reusing the same shade mechanism.
