I recently required a my car's exhaust repaired so it would pass rego so I took it to Thommo's Auto Repair in Tamar street Ballina. I was told by a friend that they not only did exhausts, but also rego checks and greenslips.
They fixed my exhaust (or should I say my car's exhaust - my exhaust has been fine since I laid off the beans) , had me rego checked, green slipped, and back on the road in under 3 hours.
The price was O.K. (not wonderful / not exorbitant) and the staff were friendly and helpful.
