Best interior modifications?

Hey y'all,

What are the best interior modifications you've put on your F-Type?

For me, it's been carbon fiber covers on cup holders and stick-on pieces for temperature control knobs, as well as a $50 AliExpress steering wheel cover I had sewed on by a professional in my city.

For you all, what have you put in your F-Type's interior that has really set it off?
