Why This Car Is Special

The 1989 Ford Mustang GT Convertible occupies a specific and well-earned spot in Fox-body history. By 1989, Ford had refined the third-generation Mustang into a genuinely capable performance car, and the GT trim represented the top of that lineup outside of the limited-production 5.0 LX. The 5.0 High Output V8 was putting out 225 horsepower and 300 lb-ft of torque that year, numbers that gave the Mustang GT a real performance advantage over most of its contemporaries. Car and Driver consistently clocked the 5.0 GT in the low 6-second range for the 0-60 sprint during this era, which made it one of the fastest cars available at any price point when new.

What separates this particular example from the crowd is its condition and its combination of options. The odometer shows just 40 miles — this car has been essentially unused, and the undercarriage photos confirm it. The floorpan, suspension components, and frame rails are clean and black, with no rust, no rot, and no evidence of hard use or deferred maintenance. For a 35-year-old convertible, that is a meaningful detail. Convertibles in particular tend to show their age in the structure and underneath, and this one does not.

The VIN confirms this is a factory GT convertible built at the Dearborn Assembly Plant, with the 5.0 HO engine and automatic transmission as original equipment. The "45" in the body code position confirms the convertible body style. This is not a coupe converted after the fact.

Fox-body Mustang GT convertibles from 1987 through 1993 are among the most collected American cars of the late 1980s and early 1990s, and values on well-preserved, low-mile examples have been climbing steadily. The combination of the full GT aero body kit, the glass rear window, the leather interior, and the near-zero mileage makes this one of the more complete and honest examples of the model you are likely to find.

Mechanical

The heart of the 1989 Ford Mustang GT Convertible is Ford's 5.0 High Output V8, displacing 302 cubic inches. By 1987, Ford had upgraded the 5.0 HO to the sequential electronic fuel injection system — known as SEFI — which replaced the earlier speed-density EFI setup and gave the engine improved throttle response, better cold-start behavior, and more consistent power delivery across the rev range. The intake manifold is the GT-40-style upper and lower configuration that became iconic on these cars, and the valve covers wear the correct 5.0 HO badging in red, white, and blue that Fox-body enthusiasts know well.

Paired to the engine is Ford's AOD 4-speed automatic overdrive transmission. The AOD gets a mixed reputation among enthusiasts who prefer the manual, but it is mechanically sound, includes a true overdrive fourth gear for highway cruising, and suits an open-top car like this one well. The undercarriage photographs show the AOD transmission pan clearly marked with the Ford oval, and the surrounding structure is coated and clean. The rear axle housing and suspension arms have been treated and show no corrosion. The dual exhaust system is in place with both mufflers visible and intact. Braking is handled by front discs with rear drums, backed by power-assisted brakes. Power steering is factory equipped.

At just over 40 miles on the odometer, the drivetrain on this car has seen almost no use. Whether it has been stored that way from new or brought back from very low mileage, the condition underneath tells the same story — this is a car that has not been driven.

Interior

The 1989 Ford Mustang GT Convertible's interior is finished in gray leather throughout, including both the front bucket seats and the rear bench seat. The leather shows no cracking, fading, or wear — consistent with the mileage. Stitching on all seating surfaces is clean and tight. The door panels carry the correct gray finish with a red accent stripe that mirrors the exterior two-tone treatment, and the integrated power window switches sit in their factory location on each panel.

The dashboard is the revised Fox-body unit with a separate instrument cluster pod on the driver's side. The tachometer is standard on the GT, reading to 7,000 RPM with the redline marked in the appropriate range for the 5.0 HO. A full set of secondary gauges — oil pressure, temperature, voltmeter, and fuel level — are visible in the cluster. The tilt steering column is in place, and the steering wheel retains its factory-style leather-wrapped cover. Cruise control stalk and buttons are functional.

The center console separates the two front buckets and includes the AOD shifter in the correct gate position along with cup holders in the rear section of the console. An aftermarket stereo has been installed in the double-DIN slot — a minor and reversible change. The Mustang pony floor mats are present on both sides, showing the running horse logo on the driver's mat. The convertible top operates manually and is finished in black. The glass rear window is a significant detail on this car — many Fox-body convertibles originally used a plastic rear window that yellows and degrades over time, and the glass unit here eliminates that concern entirely.

Exterior

The 1989 Ford Mustang GT Convertible wears a two-tone red and silver exterior that was an available factory color combination during this model year. The red covers the upper body and hood, while silver runs along the lower body cladding, bumper covers, and rocker panels. An orange accent stripe divides the two colors along the beltline, giving the car a period-correct appearance that is immediately recognizable as a late-1980s performance machine.

The full factory GT aero body kit is in place, including the integrated front air dam with fog light openings, the body-color rocker panel extensions lettered with Mustang GT script, and the rear valance. The fog lights themselves are present in the front fascia. The hood is the GT-specific unit with a raised scoop, which does not connect to the engine in a functional capacity on this application but is correct to the GT specification. The rear of the car carries the GT spoiler on the decklid and the Mustang galloping horse badge above the rear panel. The taillights are the correct louvered red units with the sequential turn signal setup that defines this generation.

Wheels are the GT pony alloy five-spoke design, correct to the 1989 GT. The 5.0 fender badges are in place on both front fenders. The black convertible top sits cleanly on the body without gaps or misalignment. The underside of the car, photographed from multiple angles on the lift, shows a uniformly black-coated floorpan with no rust bubbling, no patch panels, and no evidence of accident repair.

Conclusion

The 1989 Ford Mustang GT Convertible is already a well-regarded collectible, and a clean, honest, low-mileage example like this one is genuinely difficult to find. Most Fox-body GTs have been driven hard, modified, or both. This car has not. The odometer reads just over 40 miles, the undercarriage is clean, the leather interior is intact, and the full factory GT specification is present — from the aero body kit and pony wheels to the glass rear window and leather seating front and rear. The 5.0 HO V8 with sequential fuel injection and the AOD automatic make it a straightforward car to live with, and the convertible body makes it a Florida car in every good sense of the word.
