10 Car Rental Tips That Save Money in Europe

Europe has some of the most well-developed road networks in the world, and renting a car unlocks destinations that trains and buses simply don't reach. But the rental industry is also known for unexpected charges, confusing insurance add-ons, and upsells at the counter. Follow these ten tips and you'll navigate it confidently.

1. 1
   Book 2–4 Weeks in Advance

   Car rental prices in Europe fluctuate like airline tickets — the fleet is finite, and as availability shrinks, prices climb. Booking 2–4 weeks ahead typically secures rates 20–40% lower than booking the week before travel. Peak summer months (July–August) and major public holidays require even more lead time. Always book with free cancellation so you can re-check prices closer to the date; if the price drops, cancel and rebook.

2. 2
   Choose Full-to-Full Fuel Policy

   Rental companies offer two main fuel policies: full-to-full (you receive a full tank and return it full) and prepaid (you pay upfront for a full tank and return it empty). Prepaid sounds convenient but you're paying for fuel you may not use, and the per-litre rate is usually higher than the pump price. Always select full-to-full. Fill up at a petrol station near the return location rather than using the company's own refuelling service, which charges a steep premium per litre.

3. 3
   Avoid Airport Pickup If You Can

   Airports charge rental companies an "airport concession fee" — a percentage of revenue paid for the right to operate on airport premises. That cost gets passed directly to you. Picking up at an off-airport location (city centre branch, a bus or train station) can reduce the base rate by 10–25%. If you arrive late at night, airport pickup may still be the most practical option, but for daytime arrivals on trips where you won't need the car immediately, consider taking public transport into town and picking up from a city branch.

4. 4
   Understand CDW Before You Arrive

   Collision Damage Waiver (CDW) is the insurance that limits your financial liability if the car is damaged. Most rentals include basic CDW but come with an excess — a deductible that can be €500–€3,000 depending on the provider and vehicle category. You can either buy a standalone excess waiver policy (from specialist insurers like insurance4carhire or RentalCover.com, typically £5–£10/day) or use a credit card that covers rental car excess. Either option is usually cheaper than buying the full waiver at the counter. Read our car rental insurance guide for the full breakdown.

5. 5
   Photograph and Video the Car Before You Drive Away

   Walk around the entire vehicle — including the roof, underneath the bumpers, and the windscreen — and record video before accepting the keys. Flag every scratch, dent, and chip with the agent and confirm it's noted on the rental agreement. Email yourself the video immediately so it's timestamped. Without this evidence, a rental company can claim damage you didn't cause. This single habit has saved countless renters from unjust damage charges on return.

6. 6
   Skip the GPS Rental

   Renting a GPS unit from the rental company typically costs €8–€15 per day, which adds €80–€150 on a ten-day trip. Your smartphone with Google Maps or Waze works better than the outdated devices rental companies provide, supports offline map downloads, and costs nothing extra. If you're concerned about data roaming, download offline maps for your destination before you depart. EU roaming rules mean data charges are the same across EU member states for most European SIM cards.

7. 7
   Bring Your Own Child Seat

   Child seat rental fees range from €5–€15 per day and can easily add €100+ to a family trip. Buying a new seat often costs less than renting one for two weeks. Alternatively, bring your own seat from home — most airlines allow car seats as free checked baggage. Your own seat is also more hygienic, properly fitted, and you know its safety history. Check airline policies before travel. See our full child seat guide for regulations by country.

8. 8
   Always Choose Unlimited Mileage

   Some budget deals come with a mileage cap — for example, 200 km per day. Cross that limit and you pay a per-kilometre rate that quickly becomes expensive on longer drives. For any trip involving real touring (Baltic road trips, Adriatic coastal drives, Alpine passes), unlimited mileage is essential. When comparing prices on aggregators like our search tool, verify mileage terms before booking. The cheapest headline rate often has the tightest mileage restrictions.

9. 9
   Read the Terms for Cross-Border Restrictions

   Many rental agreements restrict which countries the car can be taken to, and violating this voids your insurance. If you plan to cross a border — for example, driving from Lithuania into Latvia, or from Germany into Poland — confirm this is permitted in your rental agreement. Some providers charge a border crossing fee (€10–€50 per country), while others include it. Declare your intended route when booking rather than assuming it's covered. See our cross-border guide for country-specific rules.

10. 10
    Compare Aggregators, Not Just the Direct Supplier

    Booking direct with Hertz, Europcar, or Avis sounds safe but rarely gives you the best price. Aggregators like DiscoverCars, RentalCars.com, and AutoEurope negotiate volume rates that undercut the direct price — often by 20–35%. Use CarRent.lt's comparison tool to search across multiple aggregators at once, then check if the direct booking is cheaper as a final check. Also compare total price (including mandatory add-ons) rather than the headline daily rate, which can be misleading.

Quick Summary: What to Do and What to Avoid

To recap the most impactful actions: book early with free cancellation, always go full-to-full on fuel, skip GPS and the prepaid fuel option, sort your excess insurance before you travel, and photograph the car thoroughly on collection. These five habits alone will save most travellers €100–€300 on a typical European road trip.

If you're renting in Lithuania specifically, you can pick up from Vilnius Airport or Kaunas Airport — both have competitive rates when booked through a comparison site rather than direct.
