Supercharged British muscle in a Savile Row suit
The Jaguar XJR is a supercharged luxury express that has spanned multiple generations, from the X300 (1994) through X308 (1997-2003), X350 (2003-2009), and X351 (2009-2019). Once prohibitively expensive, used XJRs now offer extraordinary performance and luxury for modest money — X308 examples start under five thousand pounds. They occupy a unique space as affordable supercharged V8 luxury cars with genuine classic appeal, sitting between daily-driver practicality and weekend-toy indulgence.
We track 5 known issues across the Jaguar XJR range, including 1 rated as safety-critical. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.

X300 (1994–1997) — Engine options included the 4.0L Supercharged V8.
X308 (1997–2003) — Engine options included the 4.0L Supercharged V8. Our database flags 3 known issues on this generation, 1 of which are rated as safety-critical. The most significant concern is Subframe and mounting point structural corrosion.
X350 (2003–2009) — Engine options included the 4.2L Supercharged V8. We track 4 known issues on this generation, with 3 classified as significant. The most significant concern is Suspension joint dust cover deterioration (£150–£400 to address).
X351 (2009–2019) — Engine options included the 5.0L Supercharged V8.
The aluminium monocoque body structure on X308 XJRs suffers from galvanic corrosion where steel suspension mounting points are welded to the aluminium chassis. Road salt accelerates this process, causing structural weakness at critical load-bearing areas within 30cm of suspension, subframe, and spring mounting points. MOT data shows this generation fails structural integrity tests at 17.1 times the national fleet average at higher mileages. This is a known issue specific to Jaguar's early aluminium construction methods, resolved in later generations with improved joining techniques.
Structural failure at suspension mounting points creates immediate safety risks including loss of vehicle control, suspension collapse, or wheel detachment. Professional structural welding and reinforcement typically costs £2,000-£5,000. Cars with significant structural corrosion may be uneconomical to repair and should not be driven until assessed by a structural specialist.
Inspect the wheel arches, sills, jacking points and door bottoms carefully. Press gently on sills to check for soft spots. Look underneath for corrosion on structural components. Check the MOT history for corrosion-related advisories or failures.
The rubber dust covers (gaiters) protecting ball joints and suspension bushes on X350 XJRs degrade rapidly, failing at 251 times the national fleet average. Once the protective cover fails, dirt and moisture contaminate the joint, accelerating wear and causing premature failure of expensive suspension components. This affects both front and rear suspension systems and is particularly problematic on the complex multi-link rear setup. The issue is specific to the rubber compounds used during this generation's production period.
Failed dust covers allow rapid contamination and wear of ball joints, control arm bushes, and suspension links. Replacing individual suspension components typically costs £200-£800 per corner. If multiple components fail simultaneously due to contamination, total suspension rebuild costs can reach £3,000-£5,000.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
Wheel bearings on X308 and X350 XJRs develop excessive play at 16.1 times the national fleet average, particularly at higher mileages. The heavy weight of these luxury performance saloons, combined with the stresses from the performance-oriented suspension setup, accelerates bearing wear. Failed wheel bearings create safety risks and can damage the hub assembly, ABS sensors, and surrounding suspension components if not addressed promptly.
Failed wheel bearings can cause wheel wobble, loss of steering control, and potential wheel detachment in extreme cases. Early replacement of individual bearings costs £200-£400 per corner. If the bearing seizure damages the hub assembly or knuckle, repairs can cost £800-£1,500 per corner.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
The rubber gaiters (dust boots) protecting the steering rack on X350 XJRs fail at nearly 20 times the national fleet average. These protective covers prevent dirt and moisture from contaminating the steering rack mechanism and damaging the internal seals. Once the gaiter fails, the power steering fluid leaks out and contaminants enter the system, leading to expensive steering rack replacement. The issue appears to be related to the rubber compound quality used during this generation's production.
Failed steering rack gaiters lead to contamination of the rack mechanism, causing premature wear of internal seals and components. Early gaiter replacement costs £150-£300. If contamination damages the steering rack, replacement costs £800-£1,500 plus alignment. Continued driving with failed gaiters will result in complete power steering failure.
During the test drive, check the steering for excessive play, vibration or pulling to one side. Listen for groaning or whining when turning the wheel at low speed. Power steering fluid level and condition should be checked on hydraulic systems.
The rubber bushes in the shock absorber mountings on X308 and X350 XJRs wear excessively, failing MOT tests at 9.4 times the national fleet average. These bushes isolate the shock absorber from the body structure and control suspension geometry. When they wear, handling deteriorates and the car develops knocking noises over bumps. The issue affects both front top mounts and rear shock bushes, with the complex rear multi-link suspension being particularly vulnerable.
Worn shock absorber bushes cause deteriorated ride quality, handling precision, and increased road noise. Individual bush replacement typically costs £100-£300 per corner depending on accessibility. If multiple bushes fail simultaneously, total replacement costs can reach £800-£1,200. The car remains safe to drive but handling and comfort are compromised.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.

Based on 14k real DVSA MOT tests, the Jaguar XJR fails more often than average on several items. The biggest outlier is suspension ball joints worn at 251x the fleet average, followed by transmission joint, belt or chain worn (61x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Jaguar XJR MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 10k miles) typically costs £120–£180 at an independent garage.
The bigger-ticket items to budget for include auxiliary belt and tensioner (£200–£350).

The Jaguar XJR has some well-documented weak points, including 1 safety-critical issue that demand careful checking. The right example, properly maintained, can still be a sound purchase — but cutting corners on the pre-purchase inspection is not advisable. The X350 XJR (2003-2007) is the sweet spot: aluminium construction, revised supercharged V8 with 400bhp, no Nikasil worries, and better electrics than the X308. For the X308, target late 2001-2002 cars which have the Nikasil issue resolved. The X351 XJR (2013-2019) with the 5.0 supercharged V8 is the modern pick but prices remain high.
