I used to own the Fiat conversion - the shape of the archetypal V-dub but smaller

it did 35 mpg (UK) and was as easy to drive as a car. Sluggish but the neatest thing was that it fitted into our garage with up and over doors - which is not usually the case even with the old VW combi.

There was one based on the Citreon van (car size) that had an all plastic roof that could be raised but the current models have fixed hifh rooves. Otherwise all the ones I see would not fit in a garage that easily.

they often keep their value because they are usually second vehicals and low mileage. If not , not.
