a fox mustang is a 79-93 mustang or mercury capri. the a non mustang fox could be a ltd II, granada etc from the 80's. they were all the same underneeth it all.
the lx v8 mustang is a lightweight/ sometimes base model car. it does not have ground effects that the gt's have.
the gt was the premiere v8 (before the cobra). it was usally power everything, cruise, came with a small wing, and ground effects, fancy wheels, and ugly cheese grater taillights.
the 4 eye foxes are mustangs from 79-86 as they had 4 headlights. you either love them or hate them (im the latter). (post above me is a 4 eye)
87-93 mustangs had wrap around headlights, its a 6 peice kit, corners, headlights and markers.
in 1993 ford made 2 special mustangs, they were the cobra (street) or cobra-r (only sold to licenced racers who were in with ford). they have a different grill opening, lower nose opening, larger wing, shorter rear bumber cover, and smooth gt style side skirts ( the gt's said mustang gt the cobras said nothing) they used a more powerfull motor, only came with beefed up manuals, better suspention rates, and brakes (r version)
you will also see the term vert (convertable) hatch or hb (hatch back) or notch (notchback- has a trunk)
this is a 87-93 gt hatchback with a cobra nose on it
