Peter, a more realistic view is cost of ownership over a given period. With EV’s the higher up front purchase cost is the killer in the comparison versus ICE equivalent.
Moving to PCP mitigates this price difference and changes the comparison maths results. Basically you rent/lease the car rather than buy and own an asset.
We tend to buy and keep the workhorse household car for extended periods rather than trade in/replace after 2/3 years.
I have not been convinced that stepping onto the train of early, repeat car changing works for us. We have a Kia still within the 7 year warranty period. Very pleased with it and I don’t see a reason to exchange it early.
