True, but you won't notice a difference where you drive it most, which is low-mid range. If it's a daily driver, use 87 for the commute. Save the higher octane stuff for the weekend if you can make it work.
Wow, you could rent a manual car! and a mustang! Which rental company?
True. I would be happy with the V6 engine, but I want the performance package and premium trim. :(
You are not stuck with the base interior.... Katzkin and Leatherseats.com have FULL leather interior covers that you can customize with whatever color you like. It is not expensive ($800-$1000 for full leather seats front and back) and can be installed by yourself or an "authorized installer".
I drove a performance pack 2014 days before I bought my 15. I can say for a fact that the 15 with 3.15s feels worlds better in low end torque then the 14 with the 3.31s. I think this is actually due to changes in the factory tune and the new intake manifold.
I have an '07 GT500 and revel in the shear power and responsiveness not to mention the growl. But, I also bought a 2015 Mustang V6 Automatic transmission with the Foundry 18 inch wheel package. I wanted first a sporty, fun-car and second a comfortable daily driver. I can tell you from first hand experience, the 2015 V6 is no disappointment. It is quick off the mark and really grabs asphalt in the corners. It is smooth on the highway and comfortably quiet. You get the same body, chassis and suspension as the EB and GT for an incredibly low price. BTW the brakes are actually better than on my GT500 or a 2000 Porsche 996. I am very happy with the two-tone cloth interior with white accent stitching. The only thing I plan on adding is a Sirius Satellite radio when the kit becomes available from Ford.
I have 3.73's in my '13, and the '15 felt on par with it in the low/mid rpms, which was the surprising part. I think the intake revision, along with the MAP vs MAF is a definite plus. That's why I'm really curious what a 3.55 geared car would feel like with the auto trans. I bet with mufflers, cai, BBK shortie headers, and maybe a 73mm t/b, the '15 would be on par with my '13 or a little quicker. I've been 13.3 @ 106, so that's saying something.
Rofl $19,000? These ridiculous prices always include some scenario like being a veteran while being a recent college graduate while also having someone in your household leasing a competitor's brand, etc.
