Welcome on the forum
On the charging,
I certainly would not use an extension cable, apart from water ingress issues, it should be properly rated for the 10A current that the supplied charger takes.
On the spare,
That was an issue for me as well, but it is more than compensated by the pros of the PHEV, as a pure electrical car is not an option for us, with 2 hunting dogs, and taking in account the trips we make, the PHEV is the sensible option.
Hi TweeNeuzen, thanks for the advice, the lack of a spare tyre thing I will learn to live with cos I really like the car,
I too carry 2 dogs about in the Kodiaq (only smallish doggies) they are just loose in the boot with a dog guard, but when I get the PHEV i'm going to get a custom made car crate as much as anything to keep the back windows & everything else free of mud, I notice that the charging cables reside under the floor in the boot so I may have an issue moving the crate every time I want to access the cables unless I just leave them loose somewhere
