This is a cool press photo of a Vespa dealer in Colorado back in the day. The Rally 180 is nice, and shows some of the special US-only features. It has oil injection, the small sealed-beam headlight with a chrome bezel, small reflectors on the front mudguard, and you can just barely make out the CEV tail light at the back. Note, he's wearing cowboy boots! How cool is that! The smallframe in the background looks like a Vespa 90. If so, it would be one that was still kicking around from the first series bunch that were imported in 1964.
I'm back from vacation, and posting should resume its normal pace.
