What’s the best freebie when buying a new car?

Hey everyone! I work on marketing materials for a car brand, and I'd like to know your opinion. If you were buying a new car, what small gift (80 $) from the dealer would you actually considered useful? Or what gift would make you happy?

EDIT: Thank y’all for your comments, I didn’t expect so many reactions. You’re the best!

To answer question some of you asked: I don’t work for the car dealer, but for a company who make branded gifts. Usually orders are like "We need 100 t-shirts". This time client said "Suggest something". So that’s why I am here.
