When I was living in Chicago, I took my Jackal to Motoworks for some electrical work - adding LED's where incandescants had been. It was there first time working with Motogadget. This was 2013 or so. They were actually excited about the Jackal and said "man you gotta see this..." and led me to the service dept to ogle a Centauro on a lift. I was completely new to them and was impressed by their sincere and open 'enthusiast' attitude. I also know that they make it a point to be a big part of things like DGR and Motoblot in Chicago, supporting the scene pretty prominently. They've had Vespa a long time, so there should be few surprises with the Piaggio ecosystem. If I'm not mistaken the National Sales Mgr lives in Chicagoland as well. Id imagine he'd put his thumb on the scale when possible to support such a prominent shop...but that's pure speculation on my part.
I'd say we're pretty blessed here in the midwest as far as dealers go. Cadre (Cincy), Cleveland Moto, Motoworks (Chicago), Throttle and Co (Columbus), Rahal Piaggio (Indy) - none of those are fly by night/flash in the pan shops. I believe there are a couple in Michigan as well?
