Renting a car can completely change the way you experience a destination. Instead of depending on fixed bus or train schedules, you can explore small villages, hidden beaches, scenic roads and places that are difficult to reach by public transportation.
But finding the right rental car is not always as simple as choosing the cheapest price you see.
The final cost can depend on insurance, deposits, fuel policies, mileage, additional drivers and other rental conditions. EU consumer guidance also recommends checking your liability, inspecting the vehicle carefully at pickup and return, and understanding the rental contract before driving away.
So, before booking your next rental car, here are the most important things to know.
🚘 Why Rent a Car?
A rental car gives you much more freedom when exploring a destination.
It can be especially useful when:
- You are visiting several destinations in one trip
- You want to explore small towns and villages
- Public transportation is limited
- You are traveling with family or luggage
- You want to take a scenic road trip
- You are staying outside a major city
For destinations such as the Greek islands, Portugal, Italy, Spain, and parts of Eastern Europe, having a car can make it much easier to explore beyond the main tourist areas.
💰 Don’t Choose a Rental Car Based Only on the Cheapest Price
One of the biggest mistakes travelers make is choosing the first car with the lowest advertised daily price.
A €15-per-day rental may not necessarily be cheaper than a €25-per-day option once insurance, deposits, fuel requirements and additional charges are considered.
Before booking, check:
✔ Rental price
Look at the total price rather than only the daily rate.
✔ Deposit
Some rental companies require a deposit or card pre-authorization at pickup. EU consumer authorities specifically recommend checking whether a specified amount will be pre-authorised on your card.
✔ Insurance
Check exactly what is included and what your financial responsibility would be in case of damage or an accident.
✔ Fuel policy
Check whether the rental uses a full-to-full policy or another arrangement.
✔ Mileage
Some rentals include unlimited mileage while others may have restrictions.
✔ Additional driver
Adding another driver can sometimes increase the total cost.
✔ Cross-border travel
If you’re planning to drive the rental car into another country, tell the rental company before booking. Different documentation, insurance and other requirements may apply.
🔎 Where Can You Compare Rental Cars?
Instead of checking dozens of rental companies individually, you can use a comparison platform to see different offers in one place.
One option available through TripRefuge is DiscoverCars, which compares rental offers from multiple suppliers. Its current platform covers more than 160 countries and thousands of pickup locations.
👉 Compare Car Rental Deals with DiscoverCars
You can compare prices, pickup locations, vehicle types and rental conditions before making your decision.
Tip: Always open the full rental conditions before booking. The cheapest headline price isn’t necessarily the cheapest final price.
🛡️ Understand Your Insurance
Insurance is one of the most important parts of a rental agreement.
In the EU, rental vehicles must have third-party liability insurance, but additional coverage can apply to things such as damage to the rental vehicle, theft, vandalism or other risks.
Before collecting the car, check:
- What damage is covered?
- What is the excess?
- Is theft covered?
- Are tires and glass covered?
- Is roadside assistance included?
- Are there exclusions?
- Does the coverage apply if you cross a border?
Never assume that the phrase “full insurance” means the same thing with every rental company.
📸 Take Photos Before You Drive Away
This is one of the simplest things you can do to protect yourself.
When collecting the car:
- Walk around the entire vehicle.
- Photograph every side.
- Photograph wheels and tires.
- Photograph the interior.
- Photograph the dashboard and fuel level.
- Make sure existing damage is recorded.
- Keep your rental documentation.
EU guidance specifically recommends inspecting the vehicle carefully at both collection and return and requesting written confirmation that the vehicle was returned in good condition.
⛽ Check the Fuel Policy
Fuel policies can make a noticeable difference to the final cost.
Before booking, look for terms such as:
- Full-to-full
- Same-to-same
- Pre-purchased fuel
- Fuel surcharge
Don’t assume that every rental works the same way.
If the rental agreement requires you to return the vehicle with a full tank, keep your fuel receipt until the rental has been completely closed.
European consumer authorities have specifically highlighted the importance of clearer information about fuel policies and mandatory and optional charges in car-rental bookings.
🪪 Do You Need an International Driving Permit?
This depends on where your driving licence was issued and where you’re renting.
For EU-issued licences, an EU driving licence can generally be used throughout the EU, provided it is valid. However, requirements can differ outside the EU, so check the rules for your destination before traveling.
Also check the rental company’s own requirements, especially if you’re traveling outside the EU.
🌍 Can You Drive the Rental Car Into Another Country?
Sometimes yes, but never assume it is automatically allowed.
If your road trip crosses borders, tell the rental company when booking.
The company may need to confirm that the vehicle’s documentation, insurance and breakdown coverage allow the trip.
This is particularly important for European road trips involving several countries.
🗺️ When Is Renting a Car Worth It?
A rental car can be particularly useful for:
🏝️ Islands
Exploring beaches, villages and remote areas.
🏔️ Mountain destinations
Reaching viewpoints and small mountain towns.
🌊 Coastal road trips
Stopping whenever you find a beautiful viewpoint.
🏘️ Rural destinations
Visiting places where public transportation is limited.
👨👩👧👦 Family trips
Having space for luggage and more flexibility.
For a major city where public transportation is excellent, however, renting a car may not always be necessary.
