Hi Jes, just back, to do this job £300 should cover it, that would include what you have stated & excluding the lower pulley, but I would ask them to check this if it makes you feel better, you go to the BIG garages ( Dealers) you WILL pay big costs, the heating, lighting, staff, which is ok, but like us all we are all trying to save money, the job should take approx half a day at the most, keep hold of paper work in case of problems & warranties. also quotes BEFORE the job is started, how many miles has the car done? the belt should be changed around 60000 at the latest.
