This vintage French gas station paper model makes a fun pop up card. Maybe for "Have a great trip!" or "Life is a journey, not a destination!"
I added and subtracted here and there--a few tabs, some more roof, cut off the sides of the building and added some pop up boxes and so forth.
Tutorial is here.
