Exer Rent a Car - Fort Lauderdale International Airport, 312 SW 24th St

Even though I had paid for maximum coverage on both the vehicle and the deductible, upon arrival I was asked for an additional $950 in insurance, $25 per day for the sun pass even though I wasn't going to use it, and a hold on my card for $1200 instead of $900. The conditions were rejected due to attempted fraud, and we were left stranded. Now 20 days have passed and even though I did not collect the car for the reasons mentioned above, the assistance still has not refunded me what I initially paid. Be careful. Absolutely not recommended!

DO NOT USE

DO NOT USE They took a €800 euro deposit from us for the full excess amount. This goes as a charge on your account... they say after you take the car back the charge is removed and it takes 30 to 45 days to get access back to this amount. I handed the car back on 17th September and still have not got my money. They are telling me dont worry ill get it back...then im told I would have got it back and check the bank. We cannot afford to lose this type of money.

to avoid at all cost

We rented a car online for 110 USD; in their office we were asked to pay 500 USD more in order to have the car!!!!!!!!
Upon our refusal, they even refused to take us back to the departure point.
The rudest company I have ever seen!!!

THIEVES

We made a reservation in March to rent a car in Chios from August 28-31, 2025. When we realized Exer charged our credit card for the full amount immediately, we cancelled our reservation (in March). Although they have a 48 hour cancellation policy and we are still not close to the deadline, we can not get our money refunded after trying repeatedly. A scam!!!

Don’t rent with them

I want to complain about the scam with the car rental of this Company.
Working for an airline and use to service different car rentals is the 1st time in Greece I have been refused to rent a car due to the employee lack of customer service.
I rented a car through auto Europe establishing in the general conditions an international credit card Mastercard or Visa.
Your employee start to saying he can’t accept it any it was compliant to autoeurope conditions, he didn’t even tried to block the deposit.
Don’t rent with them

Worst service ever

Worst service ever. Hidden fees, if you don't have a credit card with the driver license name you will be charged an extra 175 Euros of hidden fees. Then you will have to pay an extra deposit of 100 euros. In the end the extra fees are more than the actual fees

Absolutely Avoid – Inflexible, Unprofessional, and Packed with Hidden Fees

I had a very disappointing and stressful experience with Exer at Mykonos Airport.

Although the rental voucher did state that a credit card was required for the deposit, I only noticed this when I landed—my mistake. I had a debit card and was ready to pay the €800 deposit, as I’ve done with other companies without issue.

What followed was even worse: I was offered shady alternatives—pay in cash, or use my debit card if I agreed to a non-refundable €100 “fee” (€20/day), which was never disclosed during booking. The process felt manipulative and untrustworthy.

Stranded at the airport, I found many reviews warning of the same—including withheld deposits and surprise charges. I had to pay over €40 for a taxi and book with another provider just to salvage my trip.

Exer also charges a €15 cleaning fee on return, unless you want to clean it yourself —something I’ve never encountered in years of hiring cars.

I strongly advise avoiding Exer entirely. It’s not worth the stress, the hidden costs, or the risk.

Extra payment for road assistance

We rented a car on Thessaloniki Airport. Pick up was ok. Car was ok, but we had to take out an extra insurance for road assistance. Otherwise road assistance would be very precious.
I feel cheated by this company.

Seems Like a Scam – No Response, No Accountability

Seems Like a Scam – No Response, No Accountability

I didn’t rent the car myself, but I was there when my partner did – and what we witnessed was truly disappointing.

After returning the car in good condition (with only a tiny scratch caused by an external issue), the rental company silently charged the entire €500 deposit without warning, without any documentation, and without responding to multiple emails.

The staff never gave a clear explanation, and communication was nonexistent. It honestly feels like they’re taking advantage of tourists – no transparency, no receipts, just a charge and silence.

If this is how Exer handles minor issues, I’d stay far away. There are plenty of other rental companies in Mykonos – this one’s not worth the risk.

I honestly don’t even know where to…

I honestly don’t even know where to start. I paid 500 euros upfront for a car I never received. The company made promise after promise, delayed everything for weeks, and then completely stopped responding. No updates, no explanations — just silence.

It feels like I’ve been scammed, plain and simple. They took my money and disappeared. Customer service is a joke — if you’re lucky enough to get a reply, it’s either copy-paste nonsense or false promises that “your car is on the way.” Spoiler: it’s not.

This isn’t just bad service — it’s theft. If you’re reading this and thinking of doing business with them, don’t. Save yourself the stress, the money, and the frustration. Companies like this should not be allowed to operate.

I’ll be reporting them to consumer protection authorities, and I recommend anyone else in this situation do the same.

Title: Unjust Deposit Charge – No Transparency, No Communication

I rented a car from Exer Car Rental – Mykonos Airport from May 26–30, 2025. Upon returning the car, I was shocked to discover that they charged me the entire €500 deposit — without providing any explanation, invoice, or proof of damage repair.

There was a minor scratch on the bumper caused by a hotel gate malfunction – not due to reckless driving or negligence. The scratch was cosmetic and not structural. Still, Exer took the full deposit without notice or communication.

I tried reaching out multiple times via email to support@exercars... info@exercars.... and their support platform. No one replied.

This company’s behavior is unprofessional and feels predatory, especially toward foreign tourists. I have now submitted a formal complaint to the European Consumer Centre (ECC Greece).

Avoid renting from Exer. There are many other rental companies in Mykonos that are honest and transparent.

Shocking

Wow, this was a once in a lifetime experience. To sum it up:

- Car was prepaid in full, incl. insurances and taxes.
- On arrival in Miami, at some scrappy backyard carpark, Exer wanted to charge me a 1000 dollars extra for all kinds of stuff, excluding 400 dollars token rent for toll (!), but including additional insurance and the rental of the car, which was already paid for (and yes, I know exactly how it works with insurance).
- I called the intermediary EconomyBookings to intervene, and waited for 20 minutes while they had an argument on the phone with Exer management.
- That same Exer management refused to talk to me in person though, but hid behind the desk employee instead.
- The intermediary then advised me to NOT pay, because it was a scam. So I went back to the airport with my two small children, trying to find alternatives.
- The printed Exer 'bill' I wanted to take was ripped out of my hand, because they did not want me to take it. I managed to take a picture of it and used it as evidence to get my money back.
- Now here we are, 6 weeks later. Today I heard the intermediary (EconomyBookings) is going to compensate me in full.

However, I felt obliged to warn others for EXER. Some people may have a good experience, but that is only a cover up for these kind of ripp offs.

Btw, I managed to rent a car at Sixt the next day, and paid even less.

Be carefull with the details

Be carefull with the details! I was travelling with a group of more than 10 people, all had rent cars from several companies and the price was about the same except this incident: I had booked a car with "full insurance" through the site economycarrentals. When I was to pick up the car I was informed that either they would bind 900 euros from my credit card or I should pay 100 euros more for insurance. Additionally, the car had more than 47.000 km on its counter...

HLG Group Tanger is a Scam!!!!

HLG Group Tanger, witch is connected to Exer is a Scam! They take money from your Visa and do not refund it. It's now been a year and we still haven't received anything back. Many times they make a promise but never keep it. Stay away from this company! They are not reliable and give you false information. The latest info is that they were also kicked out of EXER.

STAY AWAY - STAFF TRAINED TO SCAM CUSTOMERS!

STAY AWAY - STAFF TRAINED TO SCAM CUSTOMERS!
I booked a rental through DISCOVERCARS with EXERCARS at Sofia Airport – I opted for full insurance. The DISCOVERCARS voucher stated that I had to pay a balance of 205 euros at the time of pick-up.
At the office, they asked for my credit card and driver’s license. They had me sign the contract.
They took my voucher and gave me a document on the condition of the car. I drove to Veliko Tarnovo, and in the evening, I checked my credit card app: I realized that they had taken the 205 euros + 500 euros deposit + 455 euros. I phone to ask the reason for this last charge, and they told me to send an email. During the vacation, I sent five emails without ever getting a response. At the time of return, I asked for the receipt of the withdrawals and the invoice. The staff tells me that they have nothing. I have to send an email, which is useless since they do not respond. I contact DISCOVERCARS. After a series of emails, they tell me that since I paid with a debit card instead of a credit card, the rental conditions had changed.
They showed me two new clauses (not present in the voucher) where, after a series of Cyrillic characters, an additional charge ( not mentioned in the voucher) is required. Questions: Why didn’t the employee ask me to pay with a credit card? I also had a VISA. Why, when having me sign the contract, did they not inform me that the clauses had changed? Why, at the time of return, did they refuse to give me the contract, receipts, and invoice? Because they are trained to scam customers. Unfair practices are their standard
behavior (see reviews on Trustpilot). Another problem is DISCOVERCARS: why do they direct you to renters with a documented history of scamming customers? I admit I gave a debit card instead of a credit card and did not scrutinize the contract. I was counting on the correctness and honesty of EXERCARS; I did not realize I was dealing with people trained in skillful theft and fraud. Lesson learned: never again EXERCARS and their accomplices at DISCOVERCARS.

STATE ALLA LARGA – STAFF ADDESTRATO A TRUFFARE I CLIENTI!
Ho prenotato un noleggio attraverso DISCOVERCARS presso EXERCARS all’aeroporto di Sofia – Ho scelto l’assicurazione totale. IL voucher di DISCOVERCARS dice che devo versare un saldo di 205 euro al momento del ritiro.
In ufficio mi chiedono carta di credito e patente. Mi fanno firmare il contratto. Mi ritirano il voucher e mi danno un documento sullo stato dell’auto. Parto per Veliko Tarnovo e in serata controllo la app della carta di credito: vedo che hanno preso i 205 euro + 500 euro di deposito + 455 euro. Telefono per chiedere il motivo di quest’ultimo prelievo, mi rispondono di mandare una email. Nel corso della vacanza mando
5 email senza avere mai una risposta . Al momento della restituzione chiedo la ricevuta dei prelievi e la fattura. Gli addetti mi rispondono che loro non hanno nulla. Devo mandare una email, cosa inutile visto che non rispondono. Contatto DISCOVERCARS. Dopo una serie di email mi dicono che avendo io pagato con una carta di debito invece che con una carta di credito le condizioni del noleggio cambiavano. Mi mostrano due nuove clausole (non presenti nel voucher) dove dopo una serie di caratteri in cirillico si prevede una ulteriore prelievo rispetto a quanto stabilito dal voucher. Domande: perché l’impiegato non mi ha chiesto di pagare con una carta di credito? Avevo anche la VISA. Perché al momento di farmi firmare il contratto non mi ha avvisato che le clausole erano cambiate? Perché al momento della consegna si sono rifiutati di darmi contratto, ricevute e fattura? Perché sono addestrati a truffare i clienti. Le pratiche scorrette sono il loro modo standard di comportamento (vedi recensioni su Trustpilot). Un ulteriore problema è DISCOVERCARS: perché ti indirizzano verso noleggiatori che una storia documentata di truffe ai clienti?
Io ammetto di avere dato una carta di debito invece di una carta di credito, di non avere spulciato il contratto . Contavo sulla correttezza e onestà di EXERCARS, non mi sono reso conto di avere a che fare con gente addestrata al furto con destrezza e alla truffa. Lezione imparata: mai più EXERCARS e i loro complici di DISCOVERCARS.
