Yes you can.
We had a VW transporter WAV but my daughter got volatile travelling in her rubbish WC. So we terminated the lease and got a private car.
Now a year down the line she has a new much better and secure chair that will not physically fit in any car so we are having to go back to motability for a Wav hasn’t been any issues well aside the fact that finding a LWB larger wav is impossible for the next year or so as all order books on vans are closed. so relying on the nearly new market and something hopefully popping up.
End of the day they want you as a customer.
