If you think about it, its cost effective to leave it with the customer.
Removing the charger would be just as expensive as installing it as they would have to put it back to how it was before.
So why pay double for an installtion and de- installation with no benefit. They cant sell it and only scrap it, its not environmentally sound.
Homes will have to have chargers fitted anyway.
I dont understand wgy phwv doesnt get an ohmy install, it gas a plug for charging. Maybe at some point mb will offer them as well.
But if you want a phev and an ohme you. could order an ev, an after a few weeks xancel it an go for your phev modrl. Mb are quick to order an ohme install. Maybe a bit caddish bit as i said homes will need an EV charger install anyways
