But I doubt I'd buy one. Think how you use things that aren't yours. Most people don't treat them with the same respect as items they own. I'd always worry that there was some hidden, time-bomb issue lurking. The drive probably would have treated it better than rental drivers would, and it, too, would have gotten regular service.
Many dealerships keep lists of leaser customers and when they are due to come in.
See if you can find something you like among their lists. You'll have to take the sit test in various models to see how they fit. You could narrow the search by scanning various car-shopping guides for headroom dimensions. You also might consider a small pickup with four-cylinder engine. Those typically have much better headroom, give reasonable mpg, and are dirt cheap.
