It may be that the fusebox cover and 12 volt socket were standardised by Caterham at some point after 2012/2014 - I don't know. The fuse box cover was not standard on 2010/2012 age vehicles from new.
I don't think that a 12 volt power supply was offered as a new car option from 2014 onwards but I could be wrong - it is certainly not an listed option on the Caterham Cars configurator nowadays, but many people must ask if a 12 volt power supply is included?? SatNav, phone charging, etc. etc.
They have been offered as a Parts Department purchase for some years now but Caterham have no stock currently - hence my request.
Some people have taken them off to save weight, esp. if they have arranged their own 12 volt supply through the rear bulkhead or from the tunnel area..
I am hoping someone has one in good condition lying around - with or without the 12 volt socket ...
