Jaguar XJ X350 Buyer Guide
A Modern Classic Luxury Car That Still Feels Special

The Jaguar XJ has long been one of Britain’s most iconic luxury cars. When Jaguar introduced the X350 generation in 2003, it represented one of the most significant engineering leaps in the model’s history.
Combining traditional Jaguar design with advanced aluminium construction, the X350 delivered exceptional comfort, strong performance and impressive efficiency for a full-size luxury saloon.
Today the X350 is increasingly recognised as a modern classic, offering a unique driving experience and genuine luxury for a fraction of its original new price.
For buyers looking for something more distinctive than the average executive car, the X350 remains one of the most interesting options on the used market.
Aluminium Engineering – What Made the X350 Unique
Image suggestion: aluminium body structure / chassis
One of the most innovative aspects of the X350 was its all-aluminium monocoque body structure.
Rather than using traditional steel construction, Jaguar engineered the car using riveted and bonded aluminium panels. This technology, inspired by aerospace design, allowed the XJ to be both lighter and stronger than its predecessor.
Key benefits included:
• reduced vehicle weight
• improved ride and handling
• better fuel efficiency
• improved structural rigidity

Despite being larger and more spacious than the previous generation, the aluminium construction meant the X350 was around 200 kg lighter, helping to deliver the smooth and refined driving experience the XJ is known for.

Engine Options –

The X350 was available with a range of engines, but in the UK market the 2.7 TDVi V6 twin-turbo diesel quickly became the most popular choice.
Available engines included:
• 2.7 TDVi twin-turbo diesel V6
• 3.0 litre V6 petrol
• 3.5 litre V8 petrol
• 4.2 litre V8 petrol
• 4.2 litre supercharged V8 (XJR)
For most UK buyers the 2.7 TDVi diesel is the engine they will encounter.
Developed jointly by Jaguar and PSA, this twin-turbo diesel engine delivers strong torque and excellent motorway refinement, which suits the character of the XJ perfectly.
Key advantages of the diesel engine include:
• smooth and effortless performance
• strong low-down torque
• excellent motorway cruising ability
• significantly better fuel economy than petrol models
Producing around 204 bhp and strong torque, the diesel XJ feels relaxed and refined on long journeys while remaining relatively economical for a large luxury car.
This engine played a major role in making the X350 a popular executive vehicle across the UK and Europe.

Driving Experience

Despite its traditional styling, the X350 is surprisingly modern to drive.
The car features computer-controlled air suspension, which allows the XJ to glide over poor road surfaces while maintaining impressive stability at speed.
Owners often describe the driving experience as:
• exceptionally comfortable
• quiet and refined
• relaxed on long journeys
Few cars at this price point deliver such a combination of luxury and driving comfort.
Interior and Comfort

Inside the cabin the X350 continues Jaguar’s tradition of classic British luxury.
Typical interior features include:
• soft leather upholstery
• genuine wood veneer trim
• heated electric seats
• premium sound systems
• generous rear passenger space
The interior design emphasises traditional craftsmanship and comfort, which is part of the car’s enduring appeal as a modern classic.
Common Issues to Check
Like any used vehicle, there are several areas prospective buyers should check when considering an X350.
Air Suspension
The air suspension system provides excellent ride quality but compressors and suspension airbags can wear with age.
Diesel Maintenance
The 2.7 TDVi diesel engine may occasionally require attention to components such as EGR valves or DPF systems, particularly if the vehicle has mainly been used for short journeys.
Electronics
As with many luxury vehicles, the XJ includes numerous electronic systems which may occasionally require attention.
Buying from a dealer familiar with these vehicles helps ensure these areas have been properly checked before sale.

Running Costs and Ownership
Despite its luxury status, the X350 can represent excellent value for money.
Typical ownership considerations include:
• routine servicing
• tyres and brakes
• diesel fuel economy
• occasional suspension maintenance
Compared with many modern luxury cars, the X350 offers a great deal of comfort and engineering for the price.
