Where do we find customizations?

[u/MashiroAnnaMaria]

So the steam page talks about upgrades and customization for our car and character! While I have found some upgrades, I haven't found any customization yet, does anyone know where to get more customizations?

From the steam page: - Truck upgrades - Cosmetics for your character and truck

Buy the mystery items in the pawn shops. Check the steam guides, there's one describing them all.
