View the listing here.What makes the RWB 964 uniqueRAUH-Welt Begriff, the creation of Japanese builder Akira Nakai, has become a global phenomenon, transforming classic air-cooled 911s into aggressive, hand-built widebody machines with a devoted following. What sets a genuine RWB apart is that Nakai personally travels to build each car by hand, cutting and fitting the fender flares on site in a process that has become the stuff of legend, making every authentic RWB a unique, artist-signed creation rather than a bolt-on kit car. The 964 chassis, with its blend of classic air-cooled character and greater usability, is a favorite base.1990 Porsche 911 Carrera 2 Coupe RWBBring a TrailerThis example carries exceptional provenance within that world. As RWB Seattle #2, built by Nakai and signed by him along with Coujin and Martin, and fitted with the rare 930 Royal widebody, it is a genuinely significant and well-documented car in the RWB community. That combination of authentic Nakai craftsmanship, rare bodywork, and complete provenance is exactly what makes this Tenka Gomen so special and so coveted.My takeThis is a genuine and provenance-rich Rauh-Welt icon, and the appeal is an authentic Nakai-built RWB with rare bodywork and complete signatures. The hand-built Nakai pedigree, the rare 930 Royal widebody, the three key signatures, and the striking matte Bahama Yellow finish make it a standout in a surging RWB market, and its known history adds real weight.AdvertisementAdvertisementFair value sits at $130,000 to $230,000, with $175,000 the most likely result, and the crux is the untested stock engine rather than anything to do with the build. Before bidding, have a compression and leak-down test performed given the mileage and value, review the RWB documentation, and get an air-cooled specialist inspection. Handle that, and this is a genuinely collectible, artist-built Porsche.Disclaimer: This post is for informational purposes only. We are not a dealership or broker.
