Two sets of seats you mean. The car is the same. These days they don't even have to blank out the buttons because it's a touch screen anyway.

I already had heated + ventilated seats with the optional multi-contour (air based) cushions, but without the memory package, so they weren't fully electric. Then there were the different materials available. Each of these things was an option, and there were more that I didn't have that I probably didn't know. Somehow they made a profit off the car. I also had the four zone climate control as opposed to the two zone, which was also an option over the manual air conditioning. There were a ton more options present and many missing (seriously, who tf optioned the sunroof, but not adaptive cruise???)

This was a 2003 car. No subscription, you just paid for the options you wanted. In fact the sunroof necessitated different body shells according to the parts catalog. How is THAT still an option? That makes for a lot more complexity than any other item being an option.

In 2025 I would expect heated seats to be standard in any car more expensive than the very base model Dacia. Super simple tech, very easy to make, and pretty much a necessity in some areas of the world, particularly where I live.
