The AU Ford Falcon is one of the most controversial and misunderstood cars in Australian motoring history. While its styling divided opinion, the AU introduced major advances in chassis strength, safety, suspension geometry, and drivetrain reliability. Today, AU Falcons are gaining recognition as excellent value modern classics, especially performance variants like the XR6 VCT, XR8, Tickford, and TE/TS models.
If you’re considering buying an AU Falcon—whether as a daily driver, sleeper build, or future collectible—here’s what to check before handing over your money.
1. Body & Exterior – More Than Just Looks
The AU’s controversial styling hides a strong, rigid body, but neglect can still cause issues.
What to Inspect:
- Front bumper mounts (often cracked)
- Bonnet alignment and latch condition
- Rear bumper sagging
- Door seals and wind noise
- Paint fade and clear coat failure (common on lighter colours)
- Accident damage (many AUs were fleet cars)
- Rust in the boot and boot lid
Panel fit issues may indicate previous accidents rather than factory tolerances.
2. Engine Options & Known Issues
Common AU Engines:
- 4.0L SOHC inline-six
- 4.0L SOHC VCT inline-six (XR6 VCT)
- 5.0L Windsor V8 (AU Series I & II)
- 5.6L Windsor V8 (Tickford TE/TS models)
What to Check:
- Cold start timing chain noise
- Oil leaks from rocker cover and rear main seal
- Overheating (thermostats and radiators wear)
- VCT solenoid operation (XR6 VCT)
- Exhaust manifold cracks
- Engine mounts (often worn)
Tip:
The AU 4.0L six is one of the most durable Falcon engines ever built when maintained properly.
3. Transmission & Driveline
Gearbox Options:
- 5-speed manual (XR models)
- 4-speed automatic (BTR)
Inspection Points:
- Harsh or delayed automatic shifts
- Manual clutch slip or chatter
- Diff clunks or whine
- Tailshaft vibration under load
Manual XR6 and XR8 models are increasingly desirable.
4. Suspension & Steering – AU’s Strong Point
The AU introduced Control Blade rear suspension, dramatically improving handling.
What to Look For:
- Worn rear control blade bushes
- Front ball joint wear
- Sagging rear springs
- Steering rack leaks
- Uneven tyre wear (poor alignment)
When refreshed, AU Falcons handle exceptionally well—even by modern standards.
5. Brakes & Safety Systems
Check:
- ABS warning lights
- Brake pedal pulsation
- Rear handbrake adjustment
- Condition of brake lines
Performance models have better factory brakes; base models may feel underpowered.
6. Interior & Electrical Systems
Common Issues:
- Sagging roof linings
- Cracked dash trim
- Climate control failures
- Window regulator faults
- Central locking issues
A tidy interior often indicates a well-maintained car.
7. Model-Specific Buying Notes
AU Forte / Futura
- Usually ex-fleet vehicles
- Simple and reliable
- Check suspension and gearbox wear
AU XR6 / XR6 VCT
- Best value performance option
- VCT adds torque but needs maintenance
- Manuals highly sought after
AU XR8
- Windsor V8 reliability
- Rising collectability
- Check cooling and drivetrain wear
AU Tickford (TE50 / TS50 / TL50)
- Limited-production models
- Unique engines and suspension
- Verify authenticity carefully
8. Modifications vs Originality
- AU Falcons respond well to upgrades
- Engine swaps are common
- Original Tickford and XR models command higher prices
- Factory paint and trim increasingly valued
Decide whether you want:
- A daily driver
- A performance project
- A future collectible
9. Market Value & Ownership Costs
- Still affordable compared to BA/BF
- Rising interest in XR and Tickford models
- Excellent parts availability
- Cheap insurance and servicing
Final Buying Advice
Ignore the jokes—the AU Falcon is a seriously capable car. Buy the cleanest example you can find, prioritise suspension and drivetrain health, and don’t overlook unmodified XR and Tickford models. They’re already on the rise.
