2014 Jaguar XK 5.0L Petrol · 20 NB

The 5.0-litre naturally aspirated V8 petrol engine is thirsty — expect combined fuel economy in the low 20s mpg at best, dropping significantly with spirited driving. Road tax for a vehicle of this age and engine capacity is a flat-rate £165 per year, and insurance will likely fall into a high group (group 45-50 typically), so obtain quotes before committing. Servicing and parts for the XK are pricier than for mainstream marques, with major items such as tyres, brake discs, and suspension components carrying premium prices. A realistic annual running cost for a low-mileage owner would be in the region of £1,500-£2,200, dominated by fuel and insurance.

The MOT advisories over the last three tests all relate to tyres — front inner-edge wear in 2025 and rear cracking/perishing in both 2025 and 2026. On inspection, examine the front tyres specifically for uneven inner-edge wear, which can indicate worn suspension bushings or tracking misalignment rather than simply driving style. The aggregate failure data for the Jaguar XK identifies the ball joint, suspension arm, and anti-roll bar as the top three MOT failure reasons across 9,352 vehicles analysed, so pay particular attention to any knocking, wandering, or uneven tyre wear that could point to tired front suspension components. Additionally, given this car's very low annual mileage, check thoroughly for corrosion, dried-out rubber seals, brake disc surface corrosion from lack of use, and any signs of rodents nesting in the engine bay or exhaust system.
