Buses from Salta
Santiago del Estero
There are dozens of car-rental agencies: get several quotes. Typically, it’s AR$800 to AR$1000 per day, and triple that for a 4WD.
There are often advance-booking specials online. Most offer discounts for paying cash.
Companies, including international names, can be slipshod operations. Mechanical problems are common (we had a car break down on us at the Bolivian border!), and don't expect state-of-the-art roadside assistance: you're often better off sorting out minor problems yourself. Complaints are frequent.
A list of providers is available at http://turismo.salta.gov.ar. Alto Valle is considered a solid service – well priced and professional.
Always check with the Provincial Tourist Office for current road conditions. Punctures are common, so check the spare kit of your vehicle before leaving Salta.
You can’t take rental cars into Bolivia, but it's possible to head into Chile by paying a bit extra and giving a few days’ notice.
