2011 Jaguar XKR 5.0L Petrol · ST 6206

The 5.0-litre supercharged V8 returns roughly 22-25 mpg in mixed driving, dropping to around 15 mpg when driven hard — typical of this performance class. Road tax sits in a high bracket given the 5000cc engine, and insurance will be in a premium group reflecting the car's 503 bhp output and performance credentials.

Annual maintenance on an XKR of this age tends to be costly, with tyres, brake discs and pads, and specialist labour all adding up. Budget at least £1,200-£1,800 per year for routine maintenance, rising substantially if the timing chain, supercharger, or transmission requires attention. A clear service history with Jaguar specialists or recognised independent XK experts is essential for resale value and reliability.

Start with a cold start — listen for any timing chain rattle on startup, which is a known XKR issue and can lead to expensive engine repairs if the chain has stretched. Inspect the underside thoroughly for any oil residue that might indicate where the MOT-advisory engine oil leak is originating. Given the rear shock absorber bush play noted in 2023, jack the car up and check all suspension bushes, particularly the lower wishbone bushes which the model data flags as a common failure point.

Check the parking brake operation — the model aggregate data lists 'parking brake inoperative' as a top failure reason, so verify both electronic application and release. Inspect the exhaust system for corrosion, another common MOT failure on this model, particularly around the rear silencer and mounting brackets. Finally, test all electrical systems including the convertible or coupe body functions, sat-nav, climate control, and adaptive dampers, as these are complex and costly to repair on the XK platform.
