When translated to English, "carros usados en venta" means "used cars for sale" or "trucks used for sale." "Carros usados en venta" is a Spanish phrase that can be translated to any other language.
The Spanish word "carros" can translate to either "car" or "shopping cart" in English but "car" is the word that works best for this specific phrase. It is also considered a proper translation to English from Spanish by saying "car used in sale." Any of the three translations mentioned will work and are all proper in both languages. If one wanted to add the phrase "where are," "donde esta" would be added to the beginning of the Spanish phrase.
