category X car meaning FORD USA Mustang Mk3 Hatchback (09.1978 - 12.1993)

The “X” car designation you mentioned in relation to a 1987 Ford Mustang doesn’t appear to be an official Ford trim or model label for that year. Instead, the 1987 Mustang is part of the third-generation “Fox Body” Mustang lineup (1979–1993), which underwent a significant facelift in 1987 featuring a more aerodynamic front end, updated interior, and refined styling.

What “X” Car Might Refer To
The term “X car” is sometimes informally used in automotive circles to describe experimental, prototype, or special edition vehicles, but there is no widely recognized “X” model for the 1987 Mustang.

It’s possible the “X” refers to a specific aftermarket or enthusiast modification package, a regional nickname, or a mistaken reference.

The 1987 Mustang lineup mainly consisted of LX and GT trims, with the LX available in coupe, hatchback, and convertible, and the GT focused on performance with the 5.0L V8 engine.

About the 1987 Ford Mustang
The 1987 Mustang marked the first major refresh of the Fox Body, with a smoother, rounded nose inspired by the SVO model, new composite headlights, and a redesigned interior with a new dash and center console.

Engine options were pared down to a 2.3L four-cylinder with fuel injection and the popular 5.0L V8, which was highly regarded for performance and aftermarket support.

The 5.0L V8 Mustang was especially popular for its strong performance (0-60 mph in under 7 seconds) and value, making it a favorite among enthusiasts.

Common Issues to Watch For on 1987 Mustangs
Electrical gremlins: Fox Body Mustangs can suffer from aging wiring harnesses, faulty grounds, and ignition switch issues.

Rust: Check for rust in common areas like wheel wells, floor pans, and the rear quarters.

Cooling system: Radiator and thermostat failures can cause overheating.

Suspension wear: Bushings and ball joints may be worn due to age.

Fuel system: Fuel injectors and pumps may need attention after decades of use.

Engine oil leaks: Common on older 5.0L engines, especially valve cover gaskets.

The 1987 Mustang is a refreshed Fox Body model, well-loved for its blend of classic muscle car style and improved aerodynamics.

There is no official “X” car designation for the 1987 Mustang; the main trims were LX and GT.

The 5.0L V8 in the GT is the highlight, offering strong performance and a large aftermarket.

When buying, watch for typical Fox Body issues like rust, electrical faults, and wear on suspension and cooling components.

If you have seen “X” used in a specific context (e.g., a custom build or regional nickname), it might be best to clarify with the seller or community where you encountered it.
