I have not had the S3 long and have already spent much more than I liked to but Im thinking I need the cam belt done as I have no record of it ever being replaced. I have been looking on jabba sport site for prices I know I will need the belt changed and I will also get the water pump done anyway. What about the damper? If I have the belt and pump done its £350 but with damper it's £405 is it a must to have the damper done?
