Struggling to pick out stickers for my car...

My wife is only buying me one (i can buy more later obviously but right now i'm POOR!!) so I'm having a hell of a time deciding. I don't really want my car COVERED in stickers either, so what I do choose is quite important!! I mean it isn't. But it feels important.

I found this etsy seller that has a LOT of cute as fuck stickers/magnets that I'm kind of obsessed with? I like these the most: [images link to listings]

Then there's these. Assorted other things I found:

I really, really like this one. It speaks to me.

I used to have a "Watch out for critters!" Bumper sticker and this one is funny.

I also feel spoken to with this one.

This one's aspirational... I'm not a birder, yet.

These I like, but not enough to buy. Special acknowledgements :)

Honestly I think I'll end up buying the magnets at some point and swapping those out. I used to make stickers reusable by sticking them to magnets - maybe I could do this with outdoor-grade magnets? Is there such a thing as outdoor-grade magnet sheets? Or will normal ones from Michaels work?
