They are correct to a degree, insurance has def increased a lot, also manufacturers are kind of pushing back on the EV push but are still trying to move but at a slower pace perhaps? i get the increase in some petrol/diesel cars due to the threat of fines if they sell too many also some EVs have dropped in price and some have increased in price. The PHEV doesnt make sense to me but could for many others. I had one in 2014 but it spent more time in the garage broken than i had it and ive been with petrol/diesel since.
I think a lot of the time its whether a manufacturer wants to shift numbers. Ford Explorer (based on VW ID platform) has increased a lot in Q4 but Ford were running a 0% campaign since launch for private buyers till end of Sept and will prob extend it.
VW ID range has dropped a lot to make them more attractive and i suspect VW have a lot sitting ready to go and really want to move them on so lease/motability is a good way to shift metal.
Mercedes too has dropped in price for the EQA i think, poss a new model coming out and they didnt shift as many of these as they wanted to?
Many manufacturers will have to guesstimate how many RHD cars to make as the RHD versions are only sold in a small number of countries compared to LHD, these wont be converted back to LHD and resold if the UK versions dont sell, they will be stuck with them. So some will have maybe made more than they sold and now need to move them on.
Overall its an increase but still a good scheme and hopefully most will find something they like and is suitable for their needs.
