Alfa Romeo (actually cars was 100% assembled by Pininfarina, Grugliasco) began to make Series 4 Spider in June of 1989. Only 10 cars were assembled in June-July of 1989. Then 10 cars in October-November, 1989. All of them were pre-production cars for tests, arranged by the factory fake spy shots and press photo sets.
This USA Veloce version is from June, 1989 and was painted in Vinaccia Red (or Rosso Winner)
Full scale production of S4 began in December of 1989 (86 cars) and last till July 1993.
Some of the pre-production Spiders had weird options as for instance this USA Base version with European beige carpets, 15" phone dials wheels,black hand brake lever and central panel, electric mirrors switch from S3 and rear fog lights. And it had weird color.
