Troca-troca (2002) is a work by Jarbas Lopes composed of three colorful Volkswagen Beetles, originally yellow, blue, and red, whose bodywork was swapped, resulting in three multicolored cars. They were used in 2002 by the artist and a group of friends on a trip from Rio de Janeiro to Curitiba. Communication between the cars was done through an interconnected sound system.

Along the way, they stuck stickers on the windshields of cars they encountered on the road, produced from the palindrome archive of the artist Luis Andrade: “zé deserto, três é dez” (Zé Desert, Three is Ten), “a vadia saída vã” (The Vain Exit), and “e o bolero; borel oboé” (And the Bolero; Borel Oboe), among others. In 2007, after restoration, the cars once again took to the road, this time from Belo Horizonte to Brumadinho, after traveling through the surrounding communities.
