1984 Mustang Buyers Inspection Guide

Inspection Checklist

Body, Rust, And Structure

Inspect the floor pans, strut towers, windshield channels, sunroof or T-top openings, fender wells, door hinges, and window surrounds for rust.
Inspect the torque boxes for cracks or prior repairs, especially when the car shows signs of hard launches.
Inspect sunroof and T-top openings, door-hinge areas, and the metal around every window rather than treating roof and glass seals as cosmetic details.

Drivetrain And EFI

Year and induction matter: carbureted, CFI, early SEFI speed-density, SVO turbo EFI, and later mass-air swaps each need different diagnosis and documentation.
For modified EFI cars, dump KOEO/KOER codes and check IAC/IAB, TPS, vacuum leaks, O2 grounds, low voltage, 10-pin connectors, MAF conversion quality, and SPOUT/TFI behavior.
On an AOD car, verify that throttle-valve control pressure was set using the Ford procedure; the factory bulletin specifies the linkage and pressure check rather than a visual cable guess.

Special Models And Tags

1982 GTs should match GT equipment such as front air dam with fog lamps, rear spoiler, black trim, 5.0 H.O. content, and the narrow GT color palette.
SVO claims need turbo/intercooled 2.3 hardware, SVO nose/hood, biplane spoiler, five-lug wheels, four-wheel discs, interior, and correct year-specific details.
A VIN appearing in the enthusiast project's consecutive batch does not confirm an SSP, and a second DSO buck tag does not confirm one either. Require matching DSO/fleet documentation, body and DSO buck tags, period paperwork, and consistent agency equipment clues.

Photo Clues

Four-eye vs aero Fox is obvious in photos: nose, headlights, dash, taillights, and quarter glass should match the claimed year.

1983+ is the factory convertible era for Fox Mustangs; a claimed 1979-1982 factory convertible should be treated as incorrect.

SVO photos should show biplane spoiler, unique hood/nose, five-lug wheels, four-wheel discs, SVO interior, turbo plumbing, and intercooler layout.

VIN, Tag & Option Mismatch Checks

Inspect the quality and documentation of every previous-owner addition; LMR specifically warns that poor-quality added parts can turn into unexpected repair costs.

Door label and buck tag disagreements on paint, trim, sunroof/T-top, GT/SVO/SSP, engine, or transmission are useful warnings for swaps or reshells.

Known Buyer Risks

Strut-tower and floor-pan rust, torque-box cracks from hard launches, poor-quality added parts, and unresolved EFI faults are practical value warnings.
Early Fox special models are easy to tribute with wheels, stripes, and spoilers; tags and drivetrain evidence matter.

Color & Interior Database

Use paint/interior codes as a screening tool, then verify individual cars from door labels, window stickers, Marti reports where available, SVT/Shelby/registry records, or Ford build data.
