The car is bone stock with 160k miles. It's missing the head unit for the Mach 460 sound system, but other than that is complete. My first plans are to just fix what's broken (AC. pass power window, missing radio) and get it into decent shape.
After that, I'd like to do a manual swap, and focus on getting the car to handle better.
I've built both vintage musclecars (Plymouth Duster and Satellite) and both modern and vintage RWD imports (Datsun Z, 240SX's, and Supras), and so far, the Mustang seems to embody the best of both worlds.
