Personally, I’d be pushing your housing association for a decision, perhaps explaining that there are major adverse changes to the Motability scheme coming in a few months time and you have to order prior to them being implemented.
IF you can charge at home, the Enyaq is a great choice. If you can’t charge at home, personally I don’t think that any EV is suitable. Aside from the high costs of public charging (which, according to reports I read the other day are likely to rise as a result of the current issues), you’d have all the inconvenience and none of the benefits. Some people will tell you that it’s do-able, but my nephew convinced himself that he could run an EV solely on public charging and he deeply regrets his decision. He cannot wait for the lease to end so that he can revert to an ICE car.
