livery inspirations?

i've sort of been in a rutt recently trying to make livery designs for my cars. in my mind they're sort of like characters and i want to do them justice by making them look badass, but i can't land on a decent design. i usually name my cars after music that i like but i can't properly envision anything without going off of something. i'm trying to make two designs for cars named "viva! la woman" and "pearl's girl" but i am having trouble with figuring out a cool design for them. they're two very powerful cars. does anyone have any suggestions?? thank you in advance :)
