Last month we collected our new motability car, but temporarily still have our previous (non-motability) car. Due to my wife’s disability, we didn’t have to pay for car tax on the old car. Am I right in thinking that now we have a motability car, car tax will become payable on the old car? If so, it doesn’t seem to be an automatic change, as it still shows as taxed on the gov.uk site. Thanks for any clarification.
