I would like to think you are right, but not according to the "specification" on the ad on PH: Specification: Owners 2. Mind you apparently it also has a 3-litre engine. I blame "fat-finger syndrome". www.pistonheads.com/buy/listing/13050616
On Williams website, it is listed as 'new'. Although they have listed it as a 2.0L in the blurb, and a 3.0L in the spec.
