Leather Seats?

[Crazy Dazz]

Curious on this.

Maybe I'm just showing my age, but I have always liked leather seats.

So, is it just my perception, or have they become LESS common (in new cars) of late?

When looking/browsing on car sales, I often filter by features. I've noticed that even when filtered by all the latest features, only a fraction of the cars selected will have leather seats.

Is this a case of changing tastes?
Perhaps a reflection of more Vegan/Vegetarian tastes?

Or has leather become so comparatively expensive, that's it reserved for only the top-level trim, on high-end models or luxury brands?

Also, Heated Seats? Even 20 years ago these were becoming common on many imported brands, especially European, American, and Japanese.
But now I find they're less common than all the latest tech wizardry.
