Local buses cost AR$5 – more for longer distances – and require a magnetic Redbus card, which can be bought at most kiosks in denominations of AR$5 and AR$10 (the card itself costs AR$10). Most lineas (bus lines) also have internos (internal route numbers) posted in the window; for example, linea 200 might post interno 204 or 206; watch for both numbers. Internos indicate more precisely where the bus will take you.
Car-rental agencies (Avis, Localiza, Hertz and National/Alamo) are at the airport and in the city center. Hertz has surprisingly good rates at its convenient location in town, fronting Plaza Independencia.
