I cannot express how much I appreciate this place, we were stuck in Dublin with car broke down and they went out of their way to help us. Drove not once but twice to where our car was and got us out of trouble. Really decent people here would highly recommend!

I went to this place to repair the inyectors one month ago. They replaced one and fixed the other three. I paid 1,203.10eur. One month later my car shows an alert of Engine Malfunction and I go again to check if the inyectors were the problem, and to check that, they have charged me 56.75eur.
They have given me two fotocopies of the diagnosis that don't show what the real problem is.
They didn't even bothered to removed the alert. To see if it will show up again or not.
