Preliminary owner report:
I tend to judge vehicles based on how they do in comparison to my expectations and how well they fulfill their intended purpose. In both respects, I have to give my 2018 Mustang an "A+" so far. I will be taking it to the dragstrip on May 23 and then on a 600 mile road trip over Memorial Day weekend so I may have more comments after those events.
No one expects a Mustang to be much for luxury or technology. However, the Mustang checks a number of important boxes: Memory seats, BLIS, adaptive cruise, collision warning with brake support, automatic high beam headlights, rain sensing wipers, acoustic windshield, soft touch door panels, etc. In addition, the instrument cluster is a thing of beauty, adaptability and functionality. You can select any number of gauges to be displayed and choose about any color combination you like. You can have the steering feel normal, sporty firm, or comfort. You can adjust the exhaust to quiet, normal, sport or track. You can adjust the engine/transmission calibration to normal, sport, sport+, track, dragstrip or snow/wet. You can even mix & match all of these things using MyMode. The 10 speed transmission is very smooth and thankfully does not "hunt" to find the right gear. No, it won't park itself like my Lincoln can and you can't open the trunk by putting your foot under the bumper but otherwise, it has about every feature I am used to and many that I have never had before.
The seats certainly lack the adjustability or massage feature of my Lincoln but they are quite comfortable with plenty of support and enough length in the bottom cushions to provide nice thigh support. While the ride is firm, it is not at all punishing. For whatever reason, it is more comfortable than my 2016 Mustang.. possibly due to the difference in tires. Wind and road noise is surprisingly low. You can hear the exhaust but it is a beautiful sound and doesn't distract from ability to have a normal conversation with passengers. I don't know who makes the Shaker Pro sound system but it is great - better than the base Revel system in my Lincoln...probably due to the sub that is part of the shaker system and missing in the base Revel. Interior fit/finish is very good....on par with my Lincoln. Visibility out the sides and back window is also quite good considering how low the car is and the fastback design. Sync 3.3 is brilliant....same as I am accustomed to in the Lincoln.
Frankly, I really like this car....so far it exceeds my expectations and totally fulfills its intended purpose! So much so, in fact, that I will try to sell my Lincoln. Unfortunately, resale on it is miserable so we will have to think about that.
