Ace Rent a Car operates off-airport via a shuttle at Porto Airport (OPO). Economy cars in Porto start around €11–18/day ($12–20) in low season – but the cheapest, safest deal usually comes from comparing suppliers, and the north's electronic-only tolls catch out unprepared drivers. This guide covers what to expect from Ace Rent a Car in Porto, the real 2026 prices, the toll and deposit rules, and the better-rated alternatives.
Ace Rent a Car at Porto Airport – compare it against the best-rated local and broker options before booking.
Porto Airport (OPO) is a competitive market, so prices stay low outside peak summer. Here is what to expect in 2026:
Average Daily Rates at Porto Airport (OPO) by Season
Booked in advance, EUR (USD approx.)
| Season | Manual Economy | Manual Compact | Automatic Compact |
|---|---|---|---|
| Low (Nov–Feb) | €11–18 | €15–22 | €25–35 |
| Shoulder (Mar–Jun, Oct) | €18–30 | €24–38 | €38–55 |
| Peak (Jul–Aug, Easter) | €33–48 | €42–60 | €60–85 |
Automatics are scarce and much pricier – book early. All OPO cars sit in a rental village ~2 min from the terminal by free shuttle.

Compare live Porto prices →Rate prefilled with a typical off-season economy rate; change it for your dates. Budget desks hold €600–1,000 on a credit card. Pre-booked excess cover (~€5–10/day) beats the counter upsell.
Ace is a broker/franchise-style budget brand with a thin European footprint, so the actual supplier fulfilling your OPO booking can vary – read the voucher to see who you'll deal with. Trustpilot sits at 2.8/5. Treat it like any budget desk: a credit-card deposit, upsell pressure and a shuttle. Document the car carefully.
Whatever you make of Ace Rent a Car, line it up against the best-rated ways to book at OPO – and the brands that draw the most complaints.
The smart way to book Porto: DiscoverCars compares all the rental-village suppliers, shows all-inclusive pricing with free cancellation, and its full-coverage add-on (~€5–10/day) undercuts every counter. Highest-rated rental platform on Trustpilot.
CAEL is a Portuguese low-cost operator with one of the highest desk scores at Porto (8.9/10 on DiscoverCars across ~2,100 reviews). Off-airport shuttle, but clean cars and far fewer billing complaints than the big budget brands.
If you want a smooth, low-pressure counter and a newer fleet, Enterprise (which services Alamo and National at OPO) scores ~9.4/10 on DiscoverCars. Pricier than the budget desks, but fair fuel terms and minimal upsell.
Goldcar has the lowest Trustpilot scores (1.3–1.5/5): aggressive insurance upselling, large pre-auth deposits (€600–1,000), and a fuel-deposit trap. Fine only if you pre-buy full excess cover and photograph everything – otherwise the most complaint-prone desk at OPO.
Surprice is the best-scoring budget brand on Trustpilot (3.2/5) but reviews.io shows just 1.2/5 – a split signal. Off-airport shuttle. Watch deposit-in-local-currency FX and “pre-paid insurance not accepted” complaints; verify the counter terms before signing.
Porto Rental Reputation: Best vs. Worst
Trustpilot (global/PT), June 2026
The headline rate rarely includes real protection. Know the three options before the counter.
Basic CDW with a high excess; budget desks hold €600–1,000 on a credit card (more on bigger cars).
Staff push full excess waivers for roughly €12–22/day – often 2–3× the price of the same cover bought online.
Buy standalone excess cover before you travel (~€5–10/day). It reimburses any excess charged – you still leave the deposit hold and claim back, so keep photos and receipts.

7-day rental at OPO, 2026 pricing
| Option | Daily Cost | 7-Day Total | Excess Covered? |
|---|---|---|---|
| Basic CDW (included) | €0 | €0 | No (€600–1,000 hold) |
| Counter Super CDW | €12–22 | €84–154 | Mostly |
| Third-party excess (pre-booked) | €5–10 | €35–70 | Yes (reclaim) |
Watch out: the motorways right around Porto – the A28 coast road, the A41/A42 ring and several ex-SCUT roads – are electronic-toll only with no booths. A foreign car with no transponder is read by gantry cameras and fined. Fix it at pickup: either fit the rental's Via Verde transponder (tolls auto-bill to your card) or register for EASYToll at the airport exit (links your plate to a card for 30 days). The A22 in the Algarve and a few others became toll-free in 2025, but most northern electronic roads still charge.
| Fuel Type | Portugal Price | Approx. USD/Litre |
|---|---|---|
| Petrol (gasolina 95) | €1.88/L | $2.03 |
| Diesel (gasóleo) | €1.78/L | $1.92 |
Most rentals are diesel; a full compact tank (~45 L) is about €80. Supermarket and independent stations undercut the motorway.
A comparison search lines up the rental-village suppliers together, so you see the real OPO market rather than one brand's price.
November–February is cheapest (economy from ~€11–18/day); July–August is dearest. Automatics are scarce in Portugal – book 1–2 months ahead for summer.
Pre-book third-party excess cover (~€5–10/day) and turn down the €12–22/day counter policy.
Add the Via Verde device or do EASYToll at pickup so the electronic-only northern roads don't turn into fines.
A car turns Porto into a base for northern Portugal's best trips – most under 90 minutes away, though some northern motorways are electronic-toll only (see below).
Portugal's iconic wine country: terraced UNESCO vineyards and port quintas. Drive to Peso da Régua via the A4, then the famous N222 to Pinhão for the river views.
The “birthplace of Portugal” – a UNESCO medieval centre and castle, compact and walkable. Easy to pair with Braga in one day.
One of Iberia's oldest cities, with the dramatic Bom Jesus do Monte sanctuary and baroque churches.
The “Portuguese Venice” of canals and moliceiro boats, plus the candy-striped beach houses of Costa Nova 10 minutes further.
Portugal's only national park – granite mountains, waterfalls, lagoons and wild ponies. Best as a long day or an overnight.
The desks for the majors are, but all the cars sit in a rental village about 2 minutes away by free shuttle. Budget brands meet you outside and shuttle you over – read your voucher for which desk or shuttle to use.
The A28, A41/A42 ring and other northern motorways are electronic-only with no booths. Use EASYToll at the airport exit, or simplest, rent the car's Via Verde transponder so tolls auto-bill – otherwise you risk fines of €20–100+.
November to February (economy roughly €11–18/day). August is the most expensive (about 88% above the annual average); July is close behind. Book early for summer and for automatics.
Most economy cars are manual; automatics cost notably more and sell out in summer – reserve one well ahead if you need it.
Budget desks hold roughly €600–1,000 on a credit card. Pre-buy full excess cover online (~€5–10/day), decline the counter upsell, and photograph the car at pickup and return.
Not for the walkable, metro-served city centre – but yes for the Douro Valley, Peneda-Gerês and the smaller northern towns, where public transport is limited.
