We ended up getting our Sonic from Nereson in Detroit Lakes. We had to purchase one from dealer stock because if we'd ordered one just the way we wanted it, we may, or may not, have had it in time to start our daughter's college adventures.
When we talked to Gateway, they didn't have a single Sonic in stock; the only one they'd had was sold and waiting for its owner to pick it up. They didn't seem too interested in selling us a Sonic anyway, but boy did they want to put us in a Cruz!
Nereson had four in stock and the one we bought we close enough to what we wanted that we were able to make the deal on our first trip out there. We picked it up four days later, all ready to go. The people at Nereson were really good to deal with and I'd go there again. Gateway? I really don't think I'd go back there again, and we'd bought a car there before and been satisfied with them; it's why we'd gone back there to begin with.
