I have a Vespa Grande which I consider to be one of the best designs around. The simplicity of the engine and the engineering of the entire package is what I like most.
Here in California the place for Vespa moped parts is vespasupershop.com in San Diego. If you call, talk to Fabio and he will give you all the info you need to know. I've dealt with them numerous times and have never been disappointed.
I'm sure you will like Ciao once you get to know it better!
