Asking for an automatic only is a very wide spread… from a tiny Hyundai i10 to Vauxhall Vivario van.
What do you need, what do you want, do you carry a wheelchair, do you carry many passengers, do you do long journeys, what’s your budget, are you under 25…. etc ?♂️
Answer some of those questions, research the Motability website to narrow the search then start phoning dealers ?
