I would never go back to a fox from my SN95, but I would like to own one. They are two very different types of cars.
For a DD/streetcar I LOVE the looks of my car, the 5.0 is just as easy to upgrage, some minor changes, but nothing terrible. The stock gears still suck ass.
2:73s make anything feel heavy.
Fox is cool only if it's like PRISTINE. They turn into ****boxes REAL fast.
I honestly feel unsafe driving the fox. Fox interiors are poopy and right angley. The SN 95 is THE best interior to go into a mustang IMO.
Bottom line: One is a hotrod. Nothing more. It's like a car from the 60s with power windows and a stereo. The sn95 is modern refined muscle. Cool seating position, smooth as silk stock, classic lines and sound.
I'd suggest driving a well modded sn95, its just raw enough to elude, yet very civil in design. I love it.
