PHEVs been great for me, as said before, in day to day use I rarely find the battery down to empty so the car is almost always able to chop and change between power sources for efficiency. Averaging about 63mpg at the moment which is better than a colleague with an equivalent diesel over similar mileage/driving conditions. Generally can get to/from motorways or major roads under hybrid/electric power and then just sit on the engine idling along for the bulk of the journey.
Not found it that accessible to incorporate charging in journeys in my experience unfortunately. Think in April I did about 1500 miles in the week we went up to Skye. Can't remember seeing a charger anywhere we went other than the accommodation halfway there/back on the first/last days so would've had to change plans through the week to find power, or compromised on accommodation. I'm sure it'll get there, it'll have to, but seeing the amount of faulty chargers knocking around already and the queues for the fast chargers whenever I pop into Donington services it's not at a place I'd want to be relying on it just yet.
