As Otherclive has said. But I would add. Don’t be tempted to buy from a distance. Warrentee returns can be a nightmare.
Having said that. Last August I bought my 2021 van from 100 miles away, and the previous owner lived 150 miles away in a different direction. But I had a long look, and long discussion with the previous owners, who volunteered to have it serviced before taking my cash. (Which I would have demanded anyway). Also, it came with extras, and was about £2500 cheaper than a dealer.
