Sort of, You could get it factory fitted or buy it after market.
VW sold the 16S in france straight out the showroom as a production model.
A few factory built uk ordered cars did make it to the uk in RHD (Like the one i posted above) a car i would love to add to my collection.
Iirc VW built 400 in house and sold them to the public (this allowed them to apply for motorsport qualification with this engine design.)
The rest were factory approved and sold thought VW dealers or aftermarket.
VW did admit to were they got the design idea from for there 16V
