steady on chap,me thinks you are worrying too much, once the new electric stuff becomes out of warranty and a used car prospect the market will decide the value not us as dealers, it will simply be we choose to sell these or choose not too, as always time will tell which used cars we are happy to run with, as for elon musk and tesla it's looking like time will catch up with him - the established brands have laughed and thanked him for putting electric into the public domain - now they will wipe the floor with him and give him a lesson in branding - check out the latest audi etron's for starters...
for the record here are the latest new figures for may19 year on year, diesel down 18%, petrol up 1%, full electric/plug in up 81%, petrol hybrids up 35%, plug in hybrids were down 40% - probably due to loosing grant status?
the biggest challenge ahead for used dealers will not be how to value these cars but as always how to dodge the ones with issues, future appraisals - ears & eyes might not be enough !!
