Cosmetically, I don't think the car is bad, but I think they could have done better. I kind of like the front end. It is new looking, similar to the look of the new fusion, which I really like, but still identifiable as a mustang. I also kind of like the rear end. It is reminiscient of the 69/70 Mustang Mach1, which in my opinion is still the best looking Mustang that has ever been made. The problem is that front end, and that back end DO NOT belong on the same car! I'm generally not a big fan of the whole retro thing, but if it is done right, like the new Challengers, it really can look good. However having half the car look retro, and the other half of the car look new, you just end up with an overall look that is confused and doesn't know what it was trying to do.
As far as interior goes, there really haven't been many newer cars whose interior I find at all pleasing, and this is no exception. This new Mustang's interior does look like an improvement over the previous model, but new cars have so much stuff crammed into the interiors with display screens and navigation, and blue tooth and touch-screen radios, and backup cameras...it just makes the interior feel cramped. All I want in an interior is 6 gauges, a console with an armrest and shifter, radio and power windows within easy reach, comfortable supportive seats, and as much room to stretch out as you can give me, and for some reason NOBODY wants to offer that anymore!
Now that I am done ranting about the exterior and interior, mechanically I am very excited about the new Mustang. It looks like they are making it smaller and lighter than the previous generation, which is great, considering the the previous 2 generations look like middle-aged overweight versions of the Mustangs from the 60s. Between that and the new suspension, it looks like this Mustang might actually have good ride and good handling simultaneously, a concept that Ford couldn't be bothered with since the MarkVIII went away in 98! The 5.0 is an incredible motor, and from the sounds of it the 2015 will have even more tweaks, so I can't argue there, and even the base 3.7 is rated at 300hp, so a plain-jane mustang won't be any slouch either. I am very curious about the 2.3 Ecoboost and where that is going to fall both in terms of power and price compared to the 5.0. Back in the SVO days, the turbo-4 was almost as powerful as the V8, but much more expensive, so it didn't sell well, and I think if they follow the same formula, they will see the same result. Also, having a 300hp base motor, if they only get 310hp out of the Ecoboost, I think very few people will spend the extra money for it, so I think that would also be a marketing failure. However if they can get about 350hp out of the turbo-4, with better braking and handling and gas mileage than either of the other 2, and if they can price it slightly under the 5.0 car, then I think they would have 3 cars that will all sell very well.
All that being said, once they come out I will probably do just what I did with the Challenger and the Ecoboost F150; build one on the website, see how much the monthly payment will be, then act like the cheap bastard I am and build something almost as fast for a lot less money, possibly using parts from these new cars when some rich kid wraps his around a pole. I may go one step further though when these come out, I may take a couple test drives just to see how it compares to my old MN12s.
