I have owned 2 Volkswagen Beetles. In terms of design and the ability to take a massive amount of punishment, they make terrific off-road vehicles.
Like any small vehicle though, they are hampered by a lack of storage space...even with a moderate size roof rack. By time you pack your belongings, extra food, fuel etc, you be soon wanting for more space.
At one time many people (including me) who used their Bug for their on/off-road travel would remove the back seat completely to make more room...This is a non starter if you have a family to bring along.
Today any Beetle in any reasonable condition that does not have the floorboards and fender joints rusted out and the front suspension not needing repair is going to command a good price and if you want a Beetle in great condition, I hope you have deep pockets.
Also consider that outside bigger areas, parts for Beetles are getting harder to find due to their now somewhat rarity. This is not idea if you are 200 miles west of nowhere....
