Late Update: This scooter made it to $6000, and did not meet reserve. The six grand price is probably close (within a grand or so) to where it should be, given the fact that it isn't perfect. About $500 worth of parts and a weekend of labor would have this scooter closer to perfect, and would probably go a long way towards bumping up the bidding. Having international shipping lined up would go even further... It is now back on ebay, with a $6500 starting bid and no reserve - so here's your chance!
Here is one thing you don't see for sale very often in the U.S., a Vespa 90 Super Sprint. This is one of the more rare Vespas, and certainly a blue chip collector scooter. Not many were made, only about five thousand, and even fewer survive today. I have seen perfect examples with 100 point restorations fetch over $15,000 in Europe. This one is nowhere near that level though. Overall, it appears to be in fairly good condition, but it is missing bits here and there, and it just doesn't have the look of a scooter that has been properly done up, considering how precious it is. It is interesting to note that despite how rare these things are, most of the parts one would need to complete a full restoration are available. Things that are obviously missing from this one are the special chrome exhaust, the legshield trim, the rear seat badge, and the license plate holder.
One other thing to be aware of is that there is a company in Germany which is making very high quality replicas of the 90SS. Since you can get all the parts to make one of these from scratch for a fraction of the cost of buying a genuine one, any possible buyer of this scooter would be well advised to do their homework. Get clear photos of the VIN numbers on this scooter, and get a lot of detailed photos of the rest of the bike. You'll want to compare them with other reliable genuine 90SS's to be sure that this isn't a replica.
