Yes, as an American, you can absolutely rent a car in Portugal. The process is straightforward, but you must meet a few key requirements. You'll need a valid U.S. driver's license that you've held for at least a year, your passport, and a major credit card in the driver's name for the security deposit. While not always mandatory, an International Driving Permit (IDP) is highly recommended. An IDP is a translated version of your license and can prevent misunderstandings with local authorities or rental agencies.
The minimum age to rent a car is typically 21, but drivers under 25 will almost always face a "Young Driver Surcharge." For the widest selection of vehicles and no young driver fees, being 25 or older is best. When you book, you'll be presented with various insurance options. Third-party liability insurance is legally required and usually included. It's crucial to strongly consider Collision Damage Waiver (CDW) and Theft Protection to minimize your financial responsibility for the rental vehicle. Pay close attention to the excess/deductible amount, which can be quite high.
Major international companies like Hertz, Avis, and Europcar operate in Portugal, alongside reliable local firms. Booking in advance online often yields better rates. Be prepared for Portugal's extensive network of electronic tolls (Via Verde). The rental company will likely offer a transponder for a daily fee, which is the most convenient way to handle tolls and avoid fines.

Sure can. It's just like renting in the States, but double-check your license. You've had it for a year, right? The real pro tip: get an International Driving Permit before you leave. It's cheap and saves a potential headache. Also, use a credit card, not a debit card, for the hold. They'll want to see your passport, too. Book ahead for the best cars and prices, especially for an automatic transmission—they're less common and cost more.

Absolutely. I rented a car in Lisbon last spring and it was seamless. The most important thing is insurance—don't just take the basic coverage. Spring for the full coverage so you're not worried about every little scratch on those narrow village roads. And be prepared for the tolls; they're all electronic. The rental company gave me a little transponder for the windshield and billed me later. It was worth the small daily fee to not have to think about it.
