What small detail or part on your Audi makes you happy?

Some silly items on my car make me illogically happy. Examples:

Pops & burbles in Sport mode always make me smile & giggle.

Flat bottom steering wheel is one of my favorite details for some reason.

Gecko puddle lights in back doors always make whoever ride back there happy, which makes me happy.

What are yours?

My little Audi TTS always turns heads,
It drives like a go-kart on steroids and always leaves me smiling after starting it up.

The leather smell in the interior, even tho my car is olddd (2006)
