Heller Ford in El Paso IL might be your best bet. It is on I-39 near Bloomington. They are an authorized service center for the new GTs. There is no one in Chicago. You would take I-74 east through Peoria to Bloomingon and pick up I-39 north to Rockford. From the quad cities probably 2-2.5 hours. Roads are good. I have two places in St Louis. Bommarito Ford in Hazelwood, MO (north side of the city) and Dave Sinclair Ford on the south side. About 4-4.5 hours from the Quad cities. You have to schedule at any of them so they have oil/parts and the certified techs are available. Oil change and brake fluid/clutch fluid will take 4-5 hours. If you want more info, send me a PM.
