Not so. Your pricing does not include servicing and maintenance as far as I can see. Thr Octopus deals DO include that. There is also the least hassle from Octopus, they look after chargr cost and installation. Going the PCH deal, you have to look after that side as well. Its ok for YOU to do that, but for the average Joe, its just another hoop and layer of hassle to go through.
Admittedly, I have not including servicing due to the Surf having a 20,000 miles or 2 years service schedule, with only one sevice required during the duration of the lease, at a cost of £260.
Through Octopus, as you suggest the car would also come with Octopus’s new Octopus Charge charger £1049. Yes I install them, but its not difficult for someone to phone there local spark or even Octopus. However I still have to go through the correct warranty procedure during warranty period even as a authorised installer.
Even if you paid Octopus to install a charger and paid for a service, you are still £2083 better off with the deal above.
That £2083 saved, will cover insurance, servicing and 2 tyres with some left over to cover charging cost.
