Your Car: Ayu Customized?

[Mintkisses]

I really want to have Ayu somewhere in or on my car, but not sure where to start >_<

There are no Ayu goods designed specifically for a car like Koda Kumi's sun visor thing she released as a tour good. Can you imagine Ayu place mats!?

Anyways, have any of you accessorized your car with anything Ayu? I was thinking of buying a sticker set and putting one on my back window, but I don't think it will last very long (weather, heat, etc.).
