Guerin Reviews 

Extremely poor service. Hired a car through Xtracars which turned out to be Guerin under a different name. Guerin tried to charge us 150 euros weeks after the rental was completed (not for tolls or damage etc but a completely unexplained charge for which they threatened to take legal action if we didn't pay). Also it says on the XtraCars/Guerin website that tyres etc are always covered, but they refused to pay for our tyre which was damaged upon collection. I highly recommend that you do not use this company.

I am an Alamo account holder as I travel quit often for work. On a recent holiday to North Portugal I reserved a car through my Alamo account and noticed it was with a third party. The rental cost for one week was €134.81. On arrival at Guerin desk I was forced to pay additional insurance of €192 and a deposit of €500 to cover toll charges. I initially thought this was excessive but thought I get refunded the balance. We're back from holidays over 5 weeks and after several emails to Guerin requesting a balance refund I have simply been ignored. My rental cost for a silly little Nissan Juke cost me almost €1'000!!! WARNING TO ALL - Avoid this company at all costs. I think I'll be cancelling my Alamo account as they don't seem to what to get involved either.
I would leave a negative mark if possible. There is absolutely zero transparency on these rental companies throughout Europe.

Only 1 Star but would not go with this company again. The whole hire process was ok and we thought the bill was settled, until 6 months later we get a bill for Tolls for the last day we were in Portgual, on 2 seperate occasions. So the tolls we assumed were all covered, but apparently not. We have receipts for tolls paid, but it seems on the day you return any vehicles then those tolls aren't registered straight away, hence the formal notice and extra charges trying to claim money back via debt collectors. This is disgusting, why should the customers have to pay for the mistake of Enterprise/Guerin not sorting this in the first place. What should have been only about £15 has turned into 2x £120 !!!

Rented two minivans from Lisbon airport for 4 days. Due to traffic we were a little bit later then foreseen and they charged us one extra day. That 1 extra day was almost the same amount as the rental price of 4 days! They also charged us a supplemental cleaning fee out of nowhere. The employee of Guerin was arrogant without limits and was smirking when charging us these extra amounts. We couldn't affor to lose time because otherwise we would have missed our flight. With these extra costs the rental price almost doubled! NEVER RENT FROM THIS COMPANY, PURE SCAM!

The worst car rental experience in my entire life of traveling! When I picked up the car nobody did a walk around to inspect the vehicle but just told me to take photos of I saw damage. The pickup in Lisbon was in a relatively dark parking garage. Upon dropping off in Faro they went over the car outside in the sun with. Fine-toothed comb, and I was charged $600 euros for literally a nick on one tire. Extremely dishonest business! This should literally be illegal.

we hired a damaged car from Guerin and when we picked it up it had a torn front tyre and the engine light was on for oil. We spent 125 euros on getting tyres replaced and engine oil and were told by the staff at Castelo Branco we would get a refund for this money after showing them a photo we took when we got the car showing the ripped tyre. All we had to do was change the NIF into Guerin's and send them the receipts. I went back to Roady and got the receipts re-issued with Guerin's NIF as requested and sent in the receipts by email. After about a month and various phone calls and emails they have just issued us a bill for 140 euros saying we owe them this!! what a nightmare...not only was there problems for us to sort out with the car, taking hours of our time at Roady but then a the amount of admin to get this done but now to be presented with a bill because apparently they recalculated the hire costs and decided we had underpaid them even though it was over a month ago the car hire and deposits etc had been returned...terrible beyond belief…after phoning today they said we were lying and it was not their procedure to get us to change the tyres and get oil replaced! Which was what the Guerin representative had told us in Castelo Branco to do…
So to sum up they will not refund the cost we paid to get tyres and oil replaced even with their NIF on the receipts, and a final
Blow of recalculating hire costs a
Month later and deciding we owe them an extra 140 euros for the hire…quite unbelievable…DO NOT HIRE A CAR FROM GUERIN!! you maybe lucky but you maybe very unlucky like us…your gamble

Hired EV from Lisbon. Car charger to approx 70%. Charging network is inexplicably bad so unable to charge the car despite several attempts. Fined €50 for the car being below 80% on return. We travelled over 100km to the airport so impossible to reach the airport with 80% even if we could charge. Staff unhelpful and extremely rude. Other rental companies do not have such restrictions. Avoid this company at all costs.

AVOID THIS COMPANY ALL COSTS. Hired a car to be collected at Lisbon airport through Enterprise in the UK. On collecting the car I noted loads of dents and scratches. The car was a Dacia Sandero… heap of junk.
I returned to Lisbon airport after our holiday and filled in the handover with all the damage I had noticed on collection.
After a week of being back in the UK I received a bill for €826!!! They sent me a picture of the smallest mark on the very bottom of the front bumper. It also had a yellow mark above it. I had not parked anywhere that could have caused this.
I have emailed and called over 17 times and received nothing back other than demands for payment. I am 100% sure I did not cause this damage. They are just out to rip off anyone they can. I wish I had the read the reviews on here first🤦🏻‍♂️ STAY AWAY from Guerin.

Booked a Renault Kadjar car to 5 people via booking.com for collection in Lisbon airport, when we arrived at the airport we were told our car was a Dacia Duster, this car is at least 2 catogreies smaller, when we pointed this out we were offered another car of the size we ordered but had to pay an extra approx 50% more to get it.
Very bad service
Never use them or Enterprise car hire who own Guerin ever again.

I paid Sunny Cars €389 in advance for a one-week rental with full insurance coverage included. That should have been the end of the story – no hidden costs, no surprises, just peace of mind.

Upon arrival in Faro, Portugal, I was directed to Guerin, the local partner of Sunny Cars. Before even picking up the car, I was forced to check in at a terminal, assisted by a Guerin employee. She insisted that I select a €300 deposit and an additional €227 insurance, claiming that Sunny Car’s coverage only applied to scratches, tire punctures, etc. and that a broader insurance was “necessary.”

This was completely misleading, since I had already paid Sunny Cars for a package clearly advertised as full coverage. The result? I spent part of my holiday arguing by email with both companies, only to be left with €227 unfairly taken from me and the bitter taste of having been deceived.

Regardless of what either company replies to this review, that money is gone forever – and it never should have been.

I strongly warn others against using these companies. I personally will never book with Sunny Cars or Guerin again, as I have already made clear to them directly.

do not try to get there at 00:01. I mean when other car companies such as SIXT, Avis, Budget, Europcar stay open and wait for their customers to arrive from slightly delayed international flights, Guerin does not offer this service. So it ended up costing me an overnight hotel stay. Furthermore the cars, are in (sub)standard condition, and not all damages are reported on exit contract. Be aware of these people. I will not rent from them again

I would give a negative star if possible. I had similar experience as recent other reviews for my rental. When we returned the car Guerin representative used a fine tooth at Lisbon Airport and claimed we scratched a back of passenger side mirror. I know we didn’t. Also when I looked at the initial pictures provided by them the scratch was there.I pointed out to the manager Carlos Pederneira and he behaved very badly with us. I sent the pictures to the customer service and received no response. It seems they don’t fix the scratch and use the same mirror scratch to commit multiple frauds. You need to file a joint action complaint for this fraud. It seems this company gets away with these frauds. I saw them commit similar fraud with other people while I was at the return counter.

Hired a car for a week in Aug 25 from Faro Airport
The car was fairly new but had a few scratches particularly on the bumpers and the wheels
Took a video and loads of pictures based on the previous reviewers experiences
When I returned the car no problem whatsoever

Did see a number of vehicles returned with what were fresh scratches so not surprised some people are charged for damage

Overall car exactly what I booked and no issues on hand back

Would use again

I would give ZERO stars if I could. This company is a SCAM. We rented a car from July 14-Aug. 3. Like many other reviewers have stated, we were not told they would take a $1000E deposit. When we returned it, they went around it with a flashlight and found a tiny scratch we had NOT done. The vehicle was completely banged up when we received it! They told us at pickup l, “Don’t worry. It’s all marked on the report.” Well it wasn’t and they proceeded to charge us $200E extra.
It’s a SCAM. Do NOT rent!!

Please read this post and save yourself the issues dealing with this company.
I read the negative reviews and changed my booking to Alamo. On arrival, I found out that Guerin operates Alamo in Portugal.

On return of the car, the employee examined the car for 20 minutes and eventually noticed a old 'scratch' on the back of the mirror. Based on my driving and where I parked the car, it is impossible that the 'scratch' occurred during my rental.

They wanted me to produce pictures of the scratch that I should have uploaded to their site at the start of the rental. They would not produce the report from the prior check in where they would have inspected the car to show that the scratch was not there. The manager would not even get up from her chair to examine the car. The manager Julie spoke to the fact that customer service is there primary concern, but failed to address the issue.

Amazingly, they decided on the spot, that the tiny scratch cost over $200 to fix and deducted it from my deposit. No evidence that the repair was or even would be completed.

Based on reviews, this appears to be a trend at Guerin and I have never posted before but feel that this is a company to be avoided at all costs.

Please reply if this influenced your decision and I will continue to provide feedback to both Guerin and Alamo and National who let their reputations be negatively impacted by this behaviour.

E’ una FRODE!!! Do NOT rent a car here! NEVER do that! They charge you at the end for damage you did NOT do and they do NOT answer any phone/emails. Stay AWAY from this company!

Avoid Guerin Rent-A-Car in Faro – Customer Service Nightmare!

If you're hiring a car in Faro, Portugal – do yourself a favor and steer clear of Guerin Rent-A-Car. They operate under National, Enterprise, and Alamo, but don’t be fooled – this is not the level of service you'd expect from those brands.

Despite preloading all my details to use their self-service kiosk, I was still directed to the counter – where the relentless upselling of insurance began. The pressure was uncomfortable and unnecessary.

To make matters worse, they placed a €1000 hold on my credit card without informing me. That’s right – before I even had the keys in hand, they had taken full payment and locked up €1000 of my credit. When I questioned it via email, I was told it was a “mandatory requirement” – which sounds official, but it’s just a corporate policy, not law.

Even after returning the car in perfect condition and with a full tank, I was told the hold would take 3–5 business days to be released, and that it was “out of their control.” Multiple follow-ups got me nothing but canned responses and excuses.

This isn’t customer service – it’s corporate stonewalling. Guerin made what should’ve been a smooth rental experience into a stressful ordeal. Plenty of other rental companies in Faro – choose one that respects your time, your wallet, and your trust.

Avoid this company ! I got charged by car trawler . They then charged me again and are refusing to refund the money , saying I signed for it , when I already explained that I’d pre paid .
Paid over £700 for 4 days driving a tiny run around !

Company charged €150 without explanation, no response after multiple written requests. Seems to be their scheme when reading the reviews. Never again!!!

I rented a car in Lisbon and it was by far the best car rental experience I have ever had !!! Fact
