Faber is the general importer of Vespa and Akrapovic in Austria and a family member runs several Vespa workshops under the same name. By the way: Fabioni is the general importer's own brand of accessories.
At the beginning of the year, the list price of the GTS Classic was massively reduced in Austria. The difference between Classic (6399€) and Super (7499€), or SuperSport (7799€) and SuperTech (7899€) is so great that many buyers opt for the Classic.
The white color has a double problem: it is available on the Super and the sporty SuperSport. A special model based on the white (+red and black) GTS Super seems the logical consequence to boost sales.
As a general importer, Faber occasionally has exclusive models/colors for the Austrian market: z.B. Vespa GTS Harlekyn
