The third-generation Ford Falcons—the XA, XB and XC—marked a major turning point for Ford Australia. With wider bodies, improved safety, stronger drivetrains and iconic styling, these Falcons are among the most recognisable and desirable classic Aussie cars, especially thanks to the legendary XB GT and Mad Max–era Falcons.
Whether you’re buying a restoration project, weekend cruiser or investment-grade muscle car, knowing what to inspect on each model can save you tens of thousands of dollars.
1. Body & Rust – Still the Biggest Risk
Despite being newer than earlier Falcons, XA–XC Falcons rust badly, especially if they’ve lived near the coast or sat unused.
High-Risk Rust Areas:
- Plenum chamber under windscreen
- Cowl panel and firewall seams
- Front chassis rails
- Rear quarter panels
- Boot floor and fuel tank area
- Lower doors and dog legs
- Roof gutters and rear window surrounds
Red Flag:
Rust in the plenum or chassis rails is expensive and labour-intensive. Walk away unless priced as a serious project.
2. Engines & Drivetrains
Third-gen Falcons offered some of Ford Australia’s strongest engine combinations.
Common Engines:
- 200 / 250 inline six
- 302 Windsor V8
- 351 Cleveland V8 (highly desirable)
- 351 Cleveland GT variants (XB/XC)
What to Check:
- Cold start oil pressure
- Timing chain rattle (Cleveland V8s)
- Overheating under load
- Oil leaks at rocker covers and rear main seal
- Correct engine codes for GT models
Tip:
A tired Cleveland rebuild can cost $12k–$20k+, especially if originality matters.
3. Transmission & Differential
Gearbox Options:
- 3-speed manual
- 4-speed Top Loader (very desirable)
- FMX automatic
- C4 automatic (six-cylinder models)
Buyer Checks:
- Smooth engagement under acceleration
- No crunching shifts
- Tailshaft vibration
- Diff whine or clunking
- Factory LSD presence (often worn or missing)
4. Suspension, Steering & Brakes
These Falcons are heavy compared to earlier models, so worn suspension is common.
Inspect For:
- Cracked front control arms
- Sagging rear leaf springs
- Steering box play
- Worn bushes throughout
- Brake fade (drums common on base models)
Many cars have been upgraded to disc brakes and polyurethane bushes, which improves drivability but affects originality on collector cars.
5. Interior & Trim Authenticity
Original interiors are becoming rare.
Check:
- Dash cracks (very common)
- Door trims and headliner condition
- Correct seat patterns for model
- Working gauges and switches
- GT-specific trim and dash clusters
Collector note:
Reproduction trim lowers value on genuine GT models but is acceptable on drivers.
6. Model-Specific Buying Notes
XA Falcon (1972–1973)
- First of the “coke bottle” shape
- Early build quality can vary
- Check for early wiring issues
- GTs command strong prices
XB Falcon (1973–1976)
- Most iconic styling (Mad Max era)
- Strong Cleveland engine options
- Highly cloned GTs and Hardtops
- Chassis fatigue possible on V8 cars
XC Falcon (1976–1979)
- Improved brakes and refinement
- Last of the big classic Falcons
- More luxury options available
- Cobra models extremely collectible
7. GT, Hardtop & Cobra Verification
Always Verify:
- Body and engine numbers
- Compliance plate details
- Correct engine and gearbox combos
- Interior and exterior trim codes
- Supporting documentation
GT replicas are extremely common.
Never rely on badges alone.
8. Modifications vs Originality
- Period-correct upgrades improve drivability
- Engine swaps hurt GT and Cobra value
- Factory colour and trim matter
- Survivor cars with patina are rising in value
Decide early whether you want:
- A driver
- A show car
- A collector investment
9. Market Value & Investment Outlook
- XA/XB prices climbing steadily
- XB GTs and Hardtops highly sought after
- XC Cobra is blue-chip Australian muscle
- Documentation drives value more than paint
Final Buying Advice
Buy the best body you can afford, verify every GT claim, and don’t underestimate rust repair costs. A straight, honest XA–XC Falcon will always outperform a shiny problem car in the long run.
