The Vespa G.S. was the top of the line scooter of the time. The G.S. 150 was arguably the most stylish scooter of all time. Certainly it ranks among the most desirable Vespas. There were several versions of the G.S. 150 with minor detail changes, and the versions were denoted by changes in the frame number. This is the third version, the VS3. These are certainly rare in the U.S., and it is unclear whether Piaggio sold the VS3 here. If they did, it was in very small numbers. We found this one in Italy, and were very excited to find such a rare scooter. This scooter is not restored, but in nice solid condition. Given its rarity, this is one that would be worth expending the effort to bring it to the next level. However, we think it looks great and you could simply ride and enjoy it as-is. Either way, you have a winner!
