I had been driving a 2006 GT for 9 years with a MT. Now at 72 years of age wanted to get an automatic. I thought I wanted another GT (3-4 years old) but needed a rental car in late May this year and got "stuck" with a 2018 Ecoboost Mustang. I was so surprised at the performance that I decided I had no need for a GT. Found a 2017 with 23K miles on it and bought it in early June. To me it feels more like a sports car than a raw muscle car and that is fine. I don't go to the track so the only time I can really use the power is accelerating onto freeways. I do miss the V8 exhaust note but see no reason for anyone to buy a GT as a daily driver -- you can't utilize the GT power, gas mileage is much lower, the GT costs at least $5K more, and the Ecoboost feels very nimble and sporty.
