What's your most unique features in your car?

I'm just wondering if there's any small touches that add alot to the overall vibe of the car. Especially in your newer/older models (mine is 2008 is250)

I find in my car these features are underrated, a bit gimmicky but I still love that it does this because it gives the car personality.

1.) Rear Glass Automatic Sun Shades - barely use it but damn it impresses my passengers

2.) Popping out door storage - expands a little bit doesn't do much else

3.) snow mode Never used it because it doesn't snow here

Edit: someone mentioned heated cooled seats in IS250 which is great for summers
