I think Julie has answered most of your questions, however the PHEV claimed 30 miles range is nearer 16 miles in the winter with the heating even with ICE unit running, we leased our PHEV when the AP was only £1699, at £2999 we would have not considered it, if we did not tow a 1500kg caravan approximately 2000 miles a year we would have gone for a full EV.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
