Take off the perfume bottle caps and set aside. Drain the cars of the perfume. Wipe clean with rubbing alcohol.
Paint the cars: one in Splendid Gold, one in Festive Red, and another in Festive Green. Allow to dry and apply additional coats as needed. Once dry, place the caps back on the cars.
Loosely wrap the trees with jute twine and tie off. Bend the trees slightly to wrap on the backs of the car. Hot glue the trees to the tops of the car trunks. Add other embellishments such as mini wreaths or presents.
