Wonderful Service at Denis Mahony Toyota
From my very first call with the service department to book a slot, the team was extremely accommodating and helpful.
On the day of my appointment, the service took exactly the amount of time they had told me in advance.
Since I didn’t have a way to get back, they kindly prioritized my car so I could take it home as quickly as possible. The wait in the lounge was actually a pleasure - very comfortable, with excellent coffee to enjoy. Overall, a seamless and highly professional car service experience!

A well thought out area for waiting for your car to be serviced with comfortable seating and plenty of charging points for your mobile. They also have free coffee and tea making facilities😄

Had a fantastic experience with Gavan! They were incredibly helpful throughout the entire process — always clear, responsive and super pleasant to deal with. Communication was excellent and they made what could have been a stressful experience feel easy and smooth. Highly recommend!

I got a great deal with Denis Mahony as I didn't know exactly what car I wanted. I had a car to exchange & had to do my research.

I needed to drive 3 cars before deciding on the one that fitted me & my lifestyle.
I admit its not the conventional way to go about upgrading your car.
I found that the sales rep didn't have alot of time for me as he was busy. Could never get him on the phone. I am delighted with my car.
I am not that familiar with but in time I'm sure I will get used to it.

Since I buy my car I have problems with this garage with over charge on the price, wrong parts, wrong registration, scratches all around the paint and more. Now after one year my car was ready for the first service 15000km, thinking is only oil change and the normal service I booked to complete the required service, my car arrives with no problem whatsoever and I have to return four times as the call me and say “ the technician forgot to secure the panel “ at my arrival they take the car and come back saying “ he forgot but was secure so is not problem”
After I left the light for Adblue tour on and a message says is not Adblue needs to fill, so I doble check my invoice and I was charged for 13.50 lts of Adblue so I call the garage asking if they genuinely as this, so I decide to return again to the garage the Answer was “ the technician forgot to connect the sensor” with this situation I have to cancel all my appointments return home and go under the car for my surprise it was Ad blue all the engine and oil leaking  I returned to the garage for the third time, I ask to speak with the manager and go under the lift to check what was the problem they come and says “ you are not believe this, the oil  filter has a leak” I say for sure I don’t believe you, I so my car at the lift and I said it was Adblue leaking they didn’t clean as the manual says And was evidently they don’t care. After 30 minutes waiting they bring my car telling me all done, but Surprised the car still with oil and Adblue on the engine they never clean or try to fix the problem properly.
The pictures are on the garage and they returned on the same condition. Not even responded the email I send as the manager is a lawyer I believe that means something anyway stay away from this people
