2004 Land Rover Defender 2.5L Diesel · S711 BBY

As a 2.5L diesel, running costs will be higher than a standard passenger car. Expect relatively low fuel economy, especially if used for heavy off-road work or towing. Tax and insurance groups for a 2004 Defender are typically moderate, but insurance premiums can rise if the vehicle is used for enthusiast driving.

Maintenance costs for a Defender can be unpredictable. While parts are widely available, specialist labour for Land Rover mechanicals can be expensive. Budget for regular replacement of consumables like tyres, which have appeared frequently in this vehicle's MOT history, and suspension components.

Start by inspecting the underside of the vehicle. The recent MOT failure for a worn rear prop shaft joint is a red flag for general drivetrain wear; check for play in the front prop shaft and differential mounts as well. You should also look closely at the braking system, specifically checking for any signs of the brake servo issues or lagging brakes noted in previous tests.

Next, check the tyres. This vehicle has a documented history of tyres being worn close to the legal limit or having damage (such as the nearside rear nail in 2025). Ensure all four tyres have healthy tread depth and are of a reputable brand. Finally, check for oil seepage around the engine block and gearbox to see if the long-standing oil leak advisory has been addressed or has worsened.
