The Fox body and it's styling did not save the Mustang. The 5 liter engine did. The Fox mustang was mediocre at best until the 5 liter 4 bbl came out. The performance sold that car despite the boring two door Fairmont styling. Had it had better styling it may have actually out sold the camaro. as it is the camaro outsold the fox mustang most years of it's existance. The Fox mustang didn't save the car, it kept it on life support until Ford could get its act together.
I have to disagree, being a diehard ford owner, the fox body mustang did not save ford, ford was fine. The truck lines have always carried ford. The fox style and the publicity that it recieved from pacing the indy 500 helped save the mustang line. The car returned to a sporty style with power, V-8 power. The 5.0 has been in play essentially from the beginning, while yes it was a 289 for several years, a simple longer stroke crank pushed the car to 302 cubes and actully 4.9L if you would like to split hairs not to mention that a 4bbl was available on all but the 6cyl engines since day 1 in 1964. the fox body came out with the v-8 as the flagship engine as well as the v-6, I-4 and turbo I-4 (pace car)that being said, the fact that ford killed the UGLY, underperforming mustang II in favor of the v-8 fox body style is what brought back the automotive passion for the mustang. The gas crisis of the 70's and 80's nearly killed the sports cars of the time.
Now back to the model, wow, I am amazed at the level of work and detail that has been put into this project. Simply amazing, i remember as a kid it was a race to see how fast I could get the cars put together, and to see if I could do it with one tube of cement or less! Paint?! that came years later, and now, it takes months to get something acomplihed as I watch and study what amazing modelers like you are doing.
