My wife and I got this car as a loaner for our regular car's recall replacement. I've never owned a performance auto, but have been a long time motorcyclist, and have owned several high performance 2-wheelers. This Mustang blows me away. The acceleration is awesome. I drove across a mountain range on a very twisty section of interstate, and have to say that was the most fun I have ever had on 4 wheels. It was solidly planted, the steering was very precise; I could easily change lines mid-curve; acceleration out of the curves was very controlled. With the top up, it feels like an upscale touring car. With the top down, it is simply sexy as h***. We're now planning to sell our SUV, and buy a new Mustang. Life is short.
My overall rating would have been higher had the V8 engine been available with a shutdown feature at highway speeds to increase overall mileage. The Corvette has it. I bought the car 9/7 and put 10K miles on it by 3/1. It came with the 265/35/20 tires and they really hold the road. Replacements will be in the close to $300 each range but they have a 500 wear rating and roll out smooth. The pre-settings on the driver power seat allows for easy exit and entrance. The interior is well done and high quality. The car is surprisingly quiet with top up or down. I bought the Mustang because I need as much trunk space as possible for my trips and unlike the hardtop convertibles, the Mustang top folds onto itself with no intrusion into an almost full size trunk. The top goes up and down quietly and fast. I downgraded the Navigation system because there is no way to alphabetize your Favorites or eliminate previous destinations individually. There is a myriad of options in the gauges and lighting features. The engine data that is displayed is far beyond the average driver. The car is a bargain in today's market. Options included automatic with paddle shifters, Nav system, tire pkg, upgraded interior, 120,000 mile warranty.
Update: I had to trade in this car on a new Honda CRV Touring. I just could not get out of it any more. My joints were in rebellion, so I am just too old (68) for this car with deep and low bucket seats. In fact, when I showed the CRV to my Aunt and Uncle, they went and traded in their Lincoln Town Car on the exact same thing. My Aunt was able to get out with no effort at all with her bad knees. That is the ONLY problem I had with using the 2017 Mustang, but it was enough. It also depreciated heavily in 7 months, from $42K to $24K KBB trade! That part is disgusting, but you get nothing for all the add-ons...beware! Original review starts here: I loved my 2014 Mustang convertible (read the review), so I got a new 2017 to have all of the active safety features and other convenience tech. What I got was something that is a huge step up in quality. In fact, a different machine, with the feel of the BMWs (Mustang handles better in my opinion - test them) I tested and a huge leap above a Camaro. It accelerates smoothly up to 121 mph (where it is electronically limited), gets up to 32 mpg on highway (with super unleaded, about 29-30 with regular). Handles much better than the GT (again, try them out side by side - I did several times - GT feels front heavy and bulky). Drives like a sports car. Has plenty of storage, something lacking in the old Mustang and non-existent in Camaros. The only things lacking is automatic braking (something I will demand in 3 years or I will switch models), and lane warning/assist. The forward collision warning is great, but it just pre-loads brakes, probably a nod to the general macho among Mustang owners, but auto braking should be an option for those of us more concerned with being alive (and the safety of others) than imagined macho. Another after market add on is a windscreen, which really makes a difference. It makes your car a two seater when in place, but I never have more than one lady friend at a time riding! :) Easy to remove, but don't get this car for a backseat anyway. One small feature I love is the center console which locks when you hit the door lock fob. I leave the top down a lot when I go into a store. This combined with alarms keeps stray hands out that stuff. All in all, a wonderful car. If they add automatic braking, I will be getting another in about 3 years.
I noted most reviews were for GTs. I own an Ecoboost Premium Convertible. Acceleration is so-so. Handling is incredible. Only two complaints are the windows controls are too far forward and the antenna is awkward if you have a car cover but it unscrews solving that. Radio actually works fine without it screwed back in. The rear seats cannot be used for passengers but I knew that in buying it. They do make good interior storage - something the old Z-3 I had was short of. Gas mileage is killer. I saw acceleration is "so-so" only due to my last car, a Lincoln LS with the V-8, being no slouch so the Ecoboost doesn't seem to add anything to that. Compared to something else maybe it'd be more impressive. So niggling complaints on what has proven to be an incredibly handling car with enough pop to satisfy. Comfort on long drives is much better than expected - the Z-3 lacked in that department. Review says car acquired in 2016 as page doesn't have 2017 as an option - car was new in August of 2017.
