Compare rates between US and local agencies
US rental car agencies like Hertz, Enterprise, and Avis are convenient and operate in many different countries abroad, but their rates are often more expensive than local or national agencies. Be sure to compare rates online through sites like Kayak or Expedia. Also, be aware of holiday and other peak tourist-season pricing.
There are a few ways to save money when renting abroad: first, specialty pricing may be offered through your airline or a travel membership programs, like AAA. Second, If you have some flexibility in your travel schedule, it’s not uncommon for local agencies to offer walk-in service for short-term and weekend car rentals. It may pay to wait until you arrive to book. And finally, thanks to the sharing economy, there are a number of popular trip and rideshare options in Europe, including BlaBlaCar and Liftshare.
