righty, on the new shape clio (MY01+) to remove the side mouldings you need to open front doors, slide the rear panel mouldings towards the open door, and slide the front door mouldings towards the rear of the car, takes a bit of effort, but its easy to do
front bumper inserts, either remove front bumper, or, grab very small flat-headed screwdriver, starting from the top of the middle insert slide screwdriver along and undo fastening clips, remove all 3 parts the same way, then refit in the same order
rear bumper - remove, its only 8 screws
