Limited numbers so the survivors are collector pieces.
They weren't very performant cars new, but they're like other classic aircooled VWs extremely easy to repair in the field which is the real key to VWs global success. Engine swaps are so quick and easy it was common to have contests at rallys.
They're fun Sunday rides, but like old British sports cars obsolete in every way but as art. They're easy to hop up and engine parts are plentiful. They're ideal for learning to wrench.
Rear engines like that one went away because aircooled VWs were utter deathtraps, but when everything was a deathtrap that wasn't a big deal.
