User: How would you book the cheapest rental car in a foreign country?
Assistant: To book the cheapest and best rental car you could start using popular aggregator websites such as Kayak and Expedia to find the best prices from large domestic car rental companies with foreign operations. Next, you can make a search for local car rental companies in the area you are travelling to, and make calls or visit their website. This may require you to speak a local language. Finally, you can utilize alternative car rental companies such as Turo if they are available in the region you are travelling to.
