Swapped the front wheels last night.
I thought I had the correct jacking point – I placed the jack on the sill under the wing.
Once the car was jacked the jack started to go through the lower part of the wing, some sort of spongy yellow foam was starting to show.
Did not completely go through, just dented the bottom part of the wing where the mudguards would go (if the car had mudguards).
Going to get alignment dome tomorrow and get assessed to ensure no damage has been caused, other than the minor cosmetic damage which can only be seen when on floor level.
Really amazed as I was sure I had the jacking point!
