I think the PHEV is a non-starter, I’d have to use public chargers as my housing association won’t let me make a parking area outside the house (I have 2 garden plots that are gravelled over).
Looking at the FHEV route fuel costs at 45-50mpg would be £600 to £800 cheaper over the 3 years but the AP is £800 to £1,000 more than the Mazda.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
