Neither Alfa Romeo GTV nor Spider 2.0 JTS were offered new in Japan. Almost all of the second-hand offerings of the Phase 3 (MY. 2003) cars are either 3.2 V6 or 2.0 T.Spark. Used car selling sites like goo-net-echange.com do not even offer an option to search for such a version. Because Phase 3 2.0 T.Spark cars were produced in very limited numbers (GTV: 127, Spider: 215), it is safe to say that many of them were destined for markets such as Japan. Interestingly the Alfa GT 2.0 JTS was offered there.
