What owners say
Our take, from owner reports
Owner sentiment is deeply divided and heavily dependent on the specific model year, engine choice, and ownership expectations.
7 problems reported (3 very frequent, 3 recurrent, 1 isolated) · high confidence
Problems owners report
- Very frequentSevere rust corrosion
Particularly on structural points like jacking points, radius arm mounts, and the rear subframe. Inadequate factory rust proofing, especially on pre-1990s models.
- Very frequentElectrical system failures
Brittle, heat-damaged wiring harnesses (especially in the V12 engine bay), Lucas electric component failures, intermittent ignition problems, faulty coaxial cable causing no-start conditions.
- Very frequentV12 engine complexity and wear
Finicky fuel injection, complex engine electronics, high maintenance requirements, poor fuel economy (cited as low as 10 MPG), inherent wear, concerns about long-term reliability without specialist care.

- RecurrentCooling system problems
Overheating, steam leaks from hoses or the block, need for radiator recore, all rubber hoses prone to degradation from engine bay heat.
- RecurrentSuspension and brake maintenance
Worn rubber bushings throughout, subframe mounts needing replacement, complex inboard rear brakes (on pre-1993 models) that are difficult and expensive to service.
- RecurrentInterior issues
Sagging headliners, cracked leather, general deterioration from age.
- IsolatedPoor fuel economy (V12)
Specifically cited as approximately 10 miles per gallon.
The version owners recommend
Models equipped with the later AJ16 4.0L inline-six cylinder engine (found in post-1993 models up to 1996) are frequently cited as the best combination of reliability, parts availability, and refinement. The AJ6 engine is also noted as a good choice, though slightly older. The consensus strongly favors the six-cylinder over the V12 for long-term ownership due to lower running costs and greater mechanical simplicity.
Competitors to consider
Owners compare it most often with the Aston Martin DB7, Jaguar XK8, Porsche 911, Porsche 928 and BMW M3.

Overall sentiment
Owner sentiment is deeply divided and heavily dependent on the specific model year, engine choice, and ownership expectations. The XJS is widely regarded as a beautiful, classic GT car with significant character and a "raffish" image, offering a unique blend of style and performance for its era. However, long-term owner reports are dominated by discussions of poor reliability, particularly for models produced during the British Leyland era (1970s and early 1980s), which suffer from severe electrical problems, inadequate rust proofing, and complex mechanical issues. The V12 engine models are singled out for being particularly finicky, high-maintenance, and fuel-inefficient, while the inline-six cylinder engines (AJ6 and later AJ16) are consistently noted as being more straightforward, reliable, and easier to live with. The consensus indicates the car is a rewarding "labour of love" or weekend project for dedicated enthusiasts with mechanical skills or a generous maintenance budget, but it is strongly advised against as a daily driver or for owners seeking a trouble-free experience.
Positioning vs competitors
Positioned as a classic, stylish grand tourer from a brand with a "slightly raffish" heritage, often seen as more accessible than contemporary Aston Martins or Rolls-Royces but less reliable and refined than German competitors like Mercedes-Benz or BMW of the same period. The inline-six models are sometimes compared favorably to the Jaguar XK8 for having more "old school charm" and being easier for DIY maintenance, though the XK8 is acknowledged as a more modern and updated driving experience. The V12 models are noted for their character but are generally considered less dependable and more complex than the V8 engines in later Jaguars or American V8s in Corvettes and Mustangs.
Recommended configurations
Inline-six cylinder engine (AJ6 or AJ16) over the V12. Manual transmission is preferred by enthusiasts but noted as rare. Convertible body style is mentioned in the context of a specific character. A comprehensive pre-purchase inspection by a specialist familiar with classic Jaguars is considered mandatory. Focus on finding a car from a dry, rust-free climate ("sunshine belt") as rust proofing is a critical weakness. A documented, extensive service history is more important than low mileage. Budget for an immediate major service including cooling system flush, replacement of all rubber hoses and suspension bushings, and inspection of the engine wiring harness.
General recommendations
Only suitable as a second car or weekend project for enthusiasts who enjoy hands-on maintenance. Not recommended as a primary daily driver or for owners without mechanical aptitude or a dedicated specialist mechanic. Before purchase, budget significantly for immediate deferred maintenance and ongoing repairs; one owner suggests budgeting for a potential engine-out rebuild on a V12. Use a trickle charger if the car will sit unused. Join dedicated owner forums for technical support and parts sourcing. Negotiate purchase price aggressively to account for the high cost of necessary refurbishment. Verify the condition of the rear subframe mounts, radius arm mounting points, and jacking points for structural rust. For V12 models, specifically check the condition of the fuel injection system, engine electronics, and ignition components like the distributor cap and notorious "coaxial cable."
Remarks
The ownership experience is fundamentally defined by the car's production era. Models from the British Leyland period (1970s to early 80s) are described as suffering from catastrophic build quality and reliability issues that permanently damaged Jaguar's reputation. Quality is noted to have improved after Jaguar's independence in the 1980s, but the company operated on a limited budget. The most significant differentiator is engine choice: the V12 is a complex, race-derived unit that requires expert care, while the inline-six engines are viewed as robust and manageable. The high cost of proper maintenance often exceeds the car's market value, making it an "uneconomic" proposition for those paying shop rates.
