€3/Day Rental Car Guide: How to Beat the System
Rental car companies make their money at the counter, not online. Know what to decline, and you keep the online price. Here’s what I’ve paid:
- €3/day in Sicily
- €4/day in Gdańsk, Poland
- €7/day in São Miguel, Azores
- €8/day in Cyprus
- €23/day (~$27) in Hawaii

Examples of deals I’ve seen on DiscoverCars:
- Barcelona, Spain – €1.80/day
- Majorca, Spain – €1.20/day
- Rome, Italy – €2.60/day
- Lisbon, Portugal – €1.10/day
- Athens, Greece – €1.90/day
- Crete, Greece – €2.90/day

The off-season gap varies by destination. Sicily in February: €3/day. In June: €20/day. Lisbon stays cheap year-round. For current prices by destination, see European Car Rental Price Comparison – updated monthly.
The Strategy
- Book through an aggregator like DiscoverCars (my review). Prices are lowest there, especially off-season.
- Purchase annual rental car excess insurance from an independent provider (as low as €50/year).
- Decline all upsold extras and insurance at the counter. You are already covered.

Insurance
Rental companies advertise low online prices on sites such as DiscoverCars. The online price gets you through the door, but once you arrive, they will try to recover the cost via desk upsells. You can decline them.
In the EU, UK, Australia, and New Zealand, your rental will include:
- Third Party Liability (TPL) – legal requirement.
- Collision Damage Waiver (CDW) / Theft Protection – with a clearly stated excess/deductible (usually €500–€2,000).
The excess is the maximum you’d pay out of pocket after a collision or theft.
Covering the Excess
Rental companies will try to sell you their own insurance (often €20/day or €150/week) to reduce your excess to €0. Decline it. Purchase an annual policy from an independent provider instead:
- Cover4Rentals (EU/EEA/UK residents) – starting at ~€75/year.
- Worldwide Insure (worldwide) – starting at ~€79/year.
- ReduceMyExcess (UK residents) – starting from ~€54/year (for 1 driver).

Important: Independent policies reimburse you after the fact. If something happens, the rental company will charge you the excess – you pay it, then file a claim with your policy provider to get it back. Buying insurance directly from the rental company means you will pay nothing if something happens – but it can quadruple the rental cost.
If you don’t want to purchase an annual policy, DiscoverCars offers their own “Full Coverage” during checkout – typically €8–€15/day. Cheaper than an annual policy for a single trip, but more expensive if you rent frequently. The supplier’s system won’t show it – expect the desk agent to push their coverage regardless.
Some credit cards come with built-in car rental coverage – check with your bank. If you own a car, your existing comprehensive policy might cover rentals too.

What’s Already Included
Unlimited mileage, airport surcharge and VAT are standard – already in the base price.
- Fuel Policy: Same-to-Same is standard. Full-to-Full is easier – no noting down the fuel level and guessing at the pump. There’s nothing you can do about which one you get.
- Tolls: vignette countries (Switzerland, Austria, Czechia, Slovakia, Slovenia) – tolls are typically included. Gate-based countries – you cover them yourself.
Age Surcharge
A driver under 25 means a Young Driver Surcharge on top of the base rate – typically €10–€30/day. On the cheapest rentals, the surcharge can cost more than the rental itself.
DiscoverCars has a dedicated age field on the search page. Fill in your age and sort the search results by “Price”. The results will already include the surcharge, no surprises at the counter.
- Under 21: Many suppliers don’t rent to those under 21 and won’t appear in results at all.
- Ages 21–24: Most suppliers add a surcharge. Enter your actual age before comparing prices or the cheapest deal can disappear at checkout.
- Ages 25–29: Surcharge still applies with some suppliers.
- Ages 70+: Senior Driver Fee applies from 70, sometimes from 65.

Additional Driver
The additional driver fee can also end up being more than the base rental cost. Typical rates across Europe are €5–€15/day, capped at 10 days.
If having an extra driver is important for you, use the “Additional driver” filter on DiscoverCars and sort by “Price”. The extra fee will be included. Some suppliers run “Additional driver for free” promos – these can end up cheaper overall than other listings once the additional driver fee is factored in.
- The fee is listed on your rental voucher but paid directly to the supplier at the desk.
- The additional driver must be present at the counter with their physical driver’s license.
- Young Driver Surcharge applies to the additional driver as well – see above.
Deposits and Credit Cards
At pick-up, the desk agent will block a security deposit on your card – usually equal to the excess (€500–€2,000). It’s an authorization hold, not a charge, but that portion of your credit limit stays frozen until they release it, which can take weeks.
A credit limit of €1,200–€2,000 covers the deposit for the majority of deals. A higher limit helps if you plan to rent multiple cars in a short period.
Getting a credit card isn’t straightforward everywhere. In some countries a steady income is required – in others, savings can be used as collateral. If eligibility is an issue, a trusted family member can add you as an additional cardholder – the card is in your name, linked to their account. Transfer them the deposit amount beforehand if needed.

Booking Tips
- Don’t Book Directly: Use an aggregator like DiscoverCars. Booking through the rental company’s own website may cost you 2x–4x more.
- Timing: In my experience, booking 1–2 weeks before the trip often beats months in advance.
- Weekly Rates: A full week can cost less than six days.
- Flexibility: Most bookings are fully refundable up to 48h before pick-up.
- Fine Print: Read the voucher thoroughly. Card requirements, grace periods are often buried there.
- Credit Card: A credit card in the driver’s name gives access to the best deals and lowest deposits.
- Debit Card: You can still find great deals using the “Debit Card” filter on DiscoverCars.
- Reviews: Safer to go for suppliers rated 8.0 or higher on DiscoverCars. Some lower-rated suppliers may invent reasons to push extras. Check Google Maps reviews as well.
- Cross-Border and Ferry Fees: Check the supplier’s policy. Usually they charge extra (€50–€90). Taking the car across a national border or onto a ferry without paying the fee voids your insurance.
Pick-Up
- What to Bring: Standard requirements (based on my last voucher – check yours).
- Driver’s License: Physical driver’s license valid for at least six months after drop-off, at least 1 year old. Non-EU license requires an International Driving Permit for rentals in Europe.
- Passport/ID: EU nationals can use a national ID card within the EU.
- Credit Card: Physical Visa/Mastercard credit card in the main driver’s name (with printed numbers). No online-only banks or prepaid cards. Valid for at least six months after drop-off.
- Early Pick-Up: Most companies will hand the car over up to an hour early. Ask at the counter.
- Pre-Paid Fuel: Decline at the counter. The rental company charges an inflated rate to fill up for you.
- Photos: Take photos and a 360° video of the car at pick-up to document pre-existing damage. Do the same at drop-off if no employee is present (after hours).
- Fuel Level: Note the fuel level at pickup and photograph the gauge. Return it at the same level.
- Drop-Off: Ask the agent to confirm the car’s condition before you leave. Ask for the closing contract. They usually send it by e-mail, but I often had to ask twice.

I often sleep in rental cars – here’s what I’ve learned: Sleeping in Rental Cars and Best Rental Cars to Sleep In.
What Can Go Wrong
Forced Insurance: Some disreputable providers will refuse to hand over the car unless you buy their insurance, regardless of your policy. They may claim your credit card doesn’t work – a tactic used to force customers into buying extras. Unfortunately, there’s no way to fight it on the spot.
DiscoverCars states on their voucher: “staff at the rental desk may not know what is covered by products booked online. The vehicle must be handed over to you after the deposit has been taken, even without the purchase of additional coverage.” On refusals: “If the supplier refuses […] please have this fact confirmed in writing […] and contact Discover Cars.”
The best protection is research before you book. DiscoverCars ratings are inflated, and they don’t make reviews easy to access – the only way I found is to Google “DiscoverCars” + city + company name. Cross-check against Google Maps reviews. AutoUnion at Warsaw Airport rates 7.2/10 on DiscoverCars, 2.5/5 on Google Maps. Be extra careful if the rating is under 8.0.
DiscoverCars sometimes masks the provider’s name before booking, showing only a rating and “DiscoverCars Choice” as the logo. You can get around it by clicking “View deal”, then “View pick-up & drop-off instructions” – this usually reveals their name and phone number.
Rental Desk Encounter: Treat this as a high-pressure sales environment. The cheaper your online rate, the harder the sales pitch is likely to be – they’re paid to recover that margin through extras. Know what you’re declining before you walk in.
Out of Hours Fees: Check desk operating hours before booking if your flight lands late. Many budget providers charge €40–€60 for after-hours pickup. It should already appear in search results once you specify your pickup time, but it isn’t always included. After-hours returns are usually free – drop the key in a box. If no employee is present, take photos of the car.
Late Return: With cheap rentals, suppliers will look for any excuse to charge you more. Don’t give them one. My last voucher allowed a 59-minute late return – check yours.
Embossed Numbers: My rental voucher for Bucharest listed a fine print requirement: the card must have embossed numbers. The provider refused to honor the voucher price because my credit card had flat-printed numbers rather than raised (embossed) ones. From what I’ve seen, some suppliers in Romania use this to force upgrades.
Honest Take: I’d be cautious booking a €1.50/day rental. The lower the rate, the more reviews I’d study before committing. There’s a real chance it doesn’t work out at the counter.
That said, I’ve rented at €3/day twice. Both times it worked. Yes, there was upselling. There were attempts to scare me into buying their insurance. But I declined. I had my own coverage, didn’t scratch the car, returned it clean. No problems either time. So yes, I think €1.50/day rentals can work too – if you know what to expect and hold firm.
