Good grief hope you're ok? !!
These cars are ageing now and most are in need of new front end bonnet cables and slam panel bonnet catch refurbishment.
Cables and catches fill with corrosion unless they were well greased early on in life and 6 monthly afterwards.
You should be able to pull the release with your little finger.
If not there is a corrosion problem or misalignment of upper catches with slam panel receptors.
Loosen the four 8mm bolts on the slam panel will temporarily ease the action.
The slam catch receptor assemblies and cables can be removed without removing slam panel so I urge owners to get these jobs done ASAP before it's too late.
Job is easier with slam panel removed and here's the link I wrote quite a few years back!
