Picked up the car this evening after having a new light fitted due to condensation and a new style wiper fitted.
All really rather painless in the end. First impressions of wiper are less rocking of the car and a cleaner sweep.
If other people have 2003 spec cars with the old style and want to get it changed, just show them your handbook with the new wiper, quote the trade description act and sit back. Worked for us.
1.4SE petrol in Merlot Red, Biege interior, 16" 5 spoke alloys, DIS, Open Sky, Elec rear windows.
