There have not been a lot of Lambrettas cropping up on eBay in the last few months. Maybe people were out riding! Now there are a few decent looking scoots for sale on the East Coast. First is a Series II Li 150 in New Hampshire. The seller does not seem to know what they have, and what little information they post is wrong. I would approach this one with care... maybe it is a scam?
Then, there is this very original looking Jet 200 Serveta near Philadelphia. It is just the kind of scoot you like to see. It has some rust, and some neglect, but appears to be un-messed with. It still has the refectors on the front fender, though the front turn signals are removed. If you cleaned it up, you could drive it as-is. Right now it is only at $850 (reserve not met). This could end up being a bargain if the reserve isn't too crazy.
