I am a member of the JEC and they have been running weekly podcasts since the UK lockdowns began.
These have been great, with a lot of interesting info (mainly motorsport), but episode 48 is talking about the X300 so I though it was worth a mention here.

This is talking about the UK range.
The X300 bit starts at around 17:50, but the whole think is worth a listen
