I stumbled upon a motorcycle junkyard in Tucson today, and low and behold, it is a "certified tomos dealer". Also it has two semi-dismantled mopeds, both honda (I think) and from the 70s. Mostly parts peds, not running. I'll post the phone number and address if anyone is interested. I got dibs on the fuel switch on one of them though.
As an aside, it carried no new anything so I wonder how it considers itself a dealer (also had a half-dismantled but in the process of being put together tomos that was at least a decade old). Since no one knew of a southern arizona moped resource I thought I'd post this.
