VW ID.3 1st Edition & Tesla M3 LR
Whilst I agree that the e-Transporter sounds like an electric van that won’t meet everybody’s needs from such a vehicle, how easy is it to reject an electric vehicle based on it not meeting it’s advertised WLTP range?Ok, as your Dad I believe you. There's no reason not to reject the van if that's the range - it's unsuitable if it is that short. Don't forget it'll get worse as it gets older, maybe only slightly but you have none to spare.
I think the best chance would be to approach the supplying dealer and say you were sold something that wasn’t fit for your stated requirements and hope they play ball.
The problem here is that the van doesn’t appear to be faulty, so straight up rejection will be difficult.
With presumably even EV Van residuals silly high though, it might give the dealer room for manoeuvre to swap it for something more suitable for the users needs.
