the dealers don't have full/complete info on the stevio quad (near as I can tell), but they do have enough to order.
I can tell you that Ken Sweet at Alfa of Portland in Maine had my order in on February 9, and that he is a good guy to deal with. they do ship vehicles.
Jonathan Schmeltz of Countryside VW in St. Paul may be a bit closer to you. They have a full-on Fiat and Alfa showroom with lots of vehicles. I have purchased 4 cars from Jonathan (he is the owner). I own a new Fiat 124 Spider and an Alfa Stelvio, both purchased from them. Tom Anderson is the sales manager for Alfa Fiat. He does a great job. You can find them on the web. Good luck to you. I love both the Fiat and the Alfa!!
