Overview

The Ford Falcon XA (1972-73), XB (1973-76), and XC (1976-79) are the second generation of the performance Falcon. These cars carried the torch from the legendary XR-XY series into a new era, one shaped by emission regulations, safety standards, and the political fallout from the "supercar scare" of 1972.

The XA introduced one of the most beautiful body shapes in Australian automotive history: the hardtop coupe. With its pillarless design, Coke-bottle hips, and aggressive stance, the XA hardtop is widely considered the best-looking Australian car ever built. The XB refined the formula with the iconic "Mad Max" look, and the XC brought the era to a close with the limited-edition Cobra, Ford's farewell to the big-cube V8 Falcon.

For buyers in 2026, the XA-XC range offers a fascinating mix of value and collectibility. Six-cylinder sedans remain affordable, while hardtop coupes and GT variants have climbed into serious money. The XC Cobra is now a genuine blue-chip collector car. This guide covers what to look for, what to avoid, and what to pay.

What to Look For

Engine

The XA-XC range shares most of its engine family with the XR-XY but with some important differences.

Inline sixes, 200ci and 250ci Crossflow: Carried over from the XR-XY series. The Crossflow six in XA-XC form is identical in principle to the earlier cars, same block, same head, same bulletproof character. All the same inspection points apply.

• The 250ci Crossflow remains the best all-round engine for a daily-driven XA-XC. It is economical, reliable, and has excellent parts availability.
• Check for the usual Crossflow issues: oil consumption from valve guide wear, timing chain rattle, and water pump weep. None of these are deal-breakers.
• Some XC models received a slightly detuned version to meet emission regulations. These run richer from the factory and may benefit from carburettor re-jetting if emissions testing is not a concern.

V8, 302ci Windsor: The 302 Windsor continued as the mid-range V8 option. In the XA-XC, it was typically paired with a 2-barrel carburettor and offered good torque without the cooling demands of the Cleveland.

• The 302 Windsor is the most affordable V8 option in the XA-XC range and makes a reliable, enjoyable engine.
• Check for the same issues as in the XR-XY: rear main seal leaks, harmonic balancer deterioration, and valve cover oil leaks.

V8, 351ci Cleveland: The 351 Cleveland was the performance engine, fitted to GT models and available as an option on other variants. In the XA-XC, emission regulations progressively reduced its output, the XC 351 made less power than the XW equivalent.

• All the Cleveland overheating concerns from the XR-XY apply here, perhaps more so. The XA-XC engine bay is tighter, which can restrict airflow to the radiator.
• Timing chain wear is the most common Cleveland issue in these cars. Listen for rattle on startup and check timing marks, if the timing is retarded beyond specification and cannot be corrected, the chain has stretched.
• The XA-XB GT 351 Cleveland is a strong engine when properly maintained. Expect $8,000-15,000 for a quality rebuild.
• The XC 351 was detuned for emissions, running a lower compression ratio and milder cam. It is still a V8 but lacks the urgency of the earlier cars.

Transmission

Toploader 4-speed manual: The Toploader continued in the XA-XC range. The same synchro wear issues apply, 2nd gear is the first to go.

• On the XA-XC, the Toploader's linkage can develop sloppiness due to worn bushings in the gear lever and the remote shift mechanism. This makes the shift feel vague and imprecise but is easy and cheap to fix with new bushings ($30-60).

C4 automatic (six-cylinder): Reliable and adequate for the six. Check fluid condition and engagement.

C6 automatic (V8): Robust unit. The C6 in XA-XC models occasionally develops band wear, symptoms include slipping on the 1-2 shift. Band adjustment is possible without removing the transmission. Full rebuild: $1,800-3,000.

FMX automatic (some V8 models): Some XA-XC V8 models used the FMX transmission instead of the C6. The FMX is less robust than the C6 and more expensive to rebuild. Check for slipping and harsh shifts. If buying a V8 auto, confirm which transmission is fitted, C6 is preferable.

Body and Rust

Rust is an even bigger concern on the XA-XC than on the XR-XY. Ford used thinner metal in some panels on the XA-XC, and the additional complexity of the hardtop body (with its frameless windows and pillarless design) creates more opportunities for water ingress.

Critical inspection points, all body styles:

• Inner guards: Same as XR-XY. Inspect where the inner guard meets the firewall and shock tower. Rust here is structural.
• Floor pans: Get underneath and probe with a screwdriver. The area under the front seats, along the transmission tunnel, and the rear footwells are the most vulnerable.
• Lower quarter panels: The bottom 150mm of each rear quarter. On coupes, this area extends further up due to the quarter panel's larger surface area.
• Boot floor and spare tyre well: Lift the mat and inspect. Water enters through taillight seals.
• A-pillars and B-pillars: The bases of both pillars are rust-prone. On the hardtop, the absence of a fixed B-pillar means the A-pillar carries more structural load, rust here is particularly concerning.
• Sills and rocker panels: Check underneath for perforation, especially behind the front wheels.
• Door bottoms: Blocked drain holes.

Hardtop-specific concerns:

• Windscreen and rear window channels: The hardtop's large glass areas mean more seal surface, and any seal failure leads to water sitting in body cavities.
• Roof gutter seams: The hardtop's roofline has seams that can separate and allow water ingress. Inspect from inside the car (headlining stains) and outside (cracking sealer along the roof edges).
• Quarter window frames: The frameless rear quarter windows rely on precise alignment. Worn regulators and guides cause wind noise, water leaks, and difficulty closing.
• Unique hardtop panels: Hardtop-specific panels (quarters, roof, pillars) are scarce and expensive. A rusty hardtop body is a far more serious problem than a rusty sedan body because replacement panels are difficult to source.

Suspension and Steering

The XA-XC uses a similar suspension layout to the XR-XY:

• Front: Upper and lower control arms with coil springs. Check ball joints, tie rod ends, and idler arm.
• Rear: Live axle with leaf springs. Check for sagging, broken leaves, and worn shackle bushings.
• Steering: Recirculating ball steering box. Check for excessive play. Power steering was available on some models, check for pump leaks and steering rack (on power steering models) leaks.

Interior and Trim

• The XA-XC interior is more complex than the XR-XY, with more trim pieces and different materials. Reproduction seat covers and door trims are available but can be expensive for GT and hardtop-specific patterns.
• The dashboard is prone to warping and cracking from sun damage. Reproduction dashpads are available for sedans ($300-600). Hardtop dashpads may differ and can be harder to source.
• GT instrument clusters (with tachometer and full instrumentation) are valuable and should be verified as genuine on GT purchases.
• The hardtop's unique door trim (different from sedan) is scarce. Check condition carefully.

Hardtop coupes command a significant premium over sedans in any specification. The XA hardtop is the most desirable body shape and the hardest to find in good condition.

Which Variant to Buy

Best value: XB sedan with the 250ci Crossflow six. The XB was produced in larger numbers than the XA, parts are plentiful, and it offers the same fundamental driving experience at a lower price. The XB's exterior styling is aggressive and distinctive, many consider it more attractive than the XC.

Best hardtop experience: XA hardtop with the 302 Windsor V8. The XA hardtop is the purest expression of the design, and the 302 Windsor provides reliable V8 performance without the cooling concerns of the Cleveland. These are rare and rising in value.

Best performance: XA or XB GT with the 351 Cleveland. The GT package includes the full performance specification, engine, brakes, suspension, and interior. These are serious performance cars with genuine Bathurst heritage.

Best investment: XC Cobra. Only 400 were built, and the Cobra was the last of the big-cube V8 Falcons. It was Ford's deliberate farewell to an era, and the market recognises its historical significance. Values have risen strongly and are likely to continue.

Avoid: Any hardtop with significant structural rust. The unique hardtop panels are scarce and extremely expensive when you can find them. A rusty hardtop coupe can easily consume $50,000+ in body repair alone. Also avoid any car with a dubious history, GT clones and fake Cobras exist in the market.

Running Costs

• Insurance: Agreed value through a classic car insurer. Budget $800-2,000/year for six-cylinder sedans, more for V8s and GTs.
• Registration: Club registration (conditional) is the most economical option at $100-300/year in most states.
• Servicing: Same as the XR-XY, the Crossflow six uses the same consumables. A basic service costs $100-150 in parts (DIY).
• Fuel: Crossflow six: 91 RON, 12-15 L/100km. Cleveland V8: 95/98 RON, 16-22 L/100km.
• Tyres: Standard sizes remain available. Budget $150-250 per tyre.
• Parts: Excellent availability for sedans and mechanical components. Hardtop-specific body panels and trim are scarce and expensive. GT-specific parts command premiums.

Final Advice

The XA-XC Falcon is a more complex proposition than the XR-XY. The hardtop body is stunningly beautiful but demanding, it requires more maintenance, is harder to restore, and costs more to keep right. If you want a hardtop, buy the best one you can find and expect to pay accordingly.

For a more practical entry into XA-XC ownership, a sedan with the Crossflow six is the smart choice. It offers the same styling era, the same driving experience, and far better parts availability.

As with all Falcons of this era, buy the best car you can afford, join a club before you buy, and get a specialist pre-purchase inspection. The knowledge within the Falcon community is extraordinary, use it.
