“Honestly: at the beginning really friendly, nothing to complain about, I was there for my oil change and service, everything was fine, suddenly this summer my AC dripped into the passenger footwell, I went there 3 times for this and it is still not fixed after 1 year!!! Meanwhile, I go there and feel like I'm their worst enemy because I'm picky about my car. I've been waiting for almost 4 weeks now for a bodywork repair that they caused. Now I'm going on vacation and got a bill for a vacation check where I had to put air in the tires myself again!!! Having to get my hands dirty myself for €117 is not okay!!!”

Ehrlich gesagt: am anfang echt freundlich, nix zu mecker, ich war für mein Ölwechsel und Service da alles gut, plötzlich sommer meine Klima tropfte in den Beifahrerfußraum, damit war ich 3 mal da und es ist immernoch nicht behoben nach 1 Jahr!!! Mittmerweile geh ich dort hin und hab das gefühl ich wäre dessen haskunde weil ich pingelig mit dem Auto bin. Ich warte jetzt schon fast 4 wochen auf eine Reparatur der Karosserie die sie verursacht haben. Jetzt führ och noch in den Urlaub bekamme eine Rechnung für einen Urlaubs check wo ich nochmal selbst Luft in die Reifen machen musste!!! Ich muss mir für 117€ noch selbs die Hände schmutzig machen das ist nicht in Ordnung!!!

“Very disappointing experience
I had a very unpleasant experience with Garage Thommes Mersch.
Two weeks ago, I booked an appointment for a general service, a front-left indicator issue, and an AC problem. I was given an appointment for 17 August. When I dropped off the car, I reconfirmed that all three issues had been noted, and the lady in the reception confirmed that they had.
I was initially told the car would be ready by 5 PM. Later, I received a call saying that a part was unavailable and that the car would need an additional day. I was asked to collect a standby car instead.
The following evening, I was informed that the service was completed and asked to collect my car. I was presented with a bill of €700+, despite receiving no quotation or prior indication of the expected cost. I paid the bill.
However, when I checked the car, I discovered that the front-left indicator issue had not been fixed. The gentleman at reception said he was not aware of what had been done because the service had been handled by his colleague, Maya. I was then asked to return the following day at 3 PM so they could look into the issue.
This meant my fourth visit to the garage. Once again, the lady in the reception arranged for a mechanic to check the car, only for me to be told that the required part was not available and that they would call me when it arrived.
What was particularly frustrating was the lack of communication and accountability. When I asked why the part had not been checked before asking me to return, or why the issue had not been addressed during the original service, the response was simply, “I DON’T KNOW.” There was no meaningful explanation or attempt to take responsibility for the inconvenience caused.
I also requested the manager’s email address so I could raise the matter formally. I received a voicemail instead, returned the call, and have still not received a response.
Overall, the experience has involved multiple unnecessary trips, poor communication, an unexpected €700+ bill, and an issue that was specifically reported when I booked the appointment but remains unresolved.
I’m sharing this review so that anyone considering Garage Thommes Mersch is aware of my experience and can ask the right questions about what will actually be checked, what parts are available, and what the expected cost will be before handing over their vehicle.”

“I hate having to leave my car there for maintenance time and time again, disappointed every single time because some apprentice works on my vehicle without supervision, small things are always missing and even up to a liter of oil, they didn't even notice the brakes were finished and so I had to change the brake discs as well”

“Reception staff non-existent and incompetent with absolutely no motivation on their part. I stopped by this morning because I am very interested in buying a Dacia Bigster and left exactly as I arrived. I am still waiting for someone to come and unlock the displayed car so I can see its interior and engine. In short, I visited this garage twice, the first and the last time.”

Personnel à l’accueil inexistante et incompétent sans aucune motivation de leur part. Je suis passé ce matin car je suis fort intéressé à l’achat d’une Dacia Bigster et suis repartie exactement comme je suis arrivé. J’attends toujours que quelqu’un vient déverrouiller la voiture exposée afin de voir son intérieur et moteur. En bref, je suis passé par ce garage deux fois, la première et la dernière.

“Following today's flooding near my workplace, I heard a noise on my vehicle, so I decided to go to this garage in an emergency. The welcome was perhaps a bit cold, but after explaining my urgent situation, the workshop manager, despite his lunch break, inspected my vehicle, allowing me to hit the road in complete safety!
Special mention for this friendly, helpful workshop manager with a professionalism that is unfortunately becoming rarer and rarer (the kia garage right next door where I went before coming to this garage, despite my distress, does not have this same priority regarding an emergency...)
I can only recommend this garage to you, without any hesitation!”

“No professionalism on their part. The reception staff is not competent and is not able to inform the customer about the work to be done or even if they are going to repair my car. My car just stayed for 3 weeks in their garage without any feedback from them. In the end, they bring out a bill of 350 euros, it's unbelievable 😑🤔
I STRONGLY ADVISE AGAINST THIS GARAGE.”

Aucun professionnalisme de leur part. Le personnel a l'accueil n'est pas compétant et n'est pas capable d'informer le client sur les travaux à faire ou même si ils vont réparer ma voiture. Ma voiture vient de rester 3 semaines dans leur garage sans aucun retour de leur part. À la fin, il me sorte une facture de 350 euros, c'est incroyable 😑🤔

“Over €400 for a first service (1 year and 20,000km) is way too expensive in my opinion.

A colleague only pays around €300 for the service of his car, 6-cylinder 3-liter engine (opposite the station in Mersch)
