Labour charges do vary at different Renault garages. Most garages are independant and therefore can set their own labour rates. It will depend on the area/size of dealer. It is very expensive to RUN a dealership and you would be amazed at the small retained profit these garages actually make. Its not a con, just economics. Shop around to find the best deal. Also, taking your car to a non franchised dealer could invalidate your 3 year warranty. Wouldnt want that to happen would we now?
