Vehicle Value Check
Vehicle Value Check
A typical 1994-1998 Land Rover Defender 110 300Tdi in decent condition is valued between £15,000 and £35,000+ [THIRD-PARTY]. At this value band, a £3,500-£5,000 rebuilt engine replacement is typically a small relative cost that protects and enhances the vehicle's classic asset value.
Our Recommendation
Our Recommendation
If the engine is otherwise healthy, a specialist head gasket repair with steel dowel upgrades is a highly viable and authentic fix. However, if the engine has high mileage, smokes, or lacks compression, a full reconditioned replacement is the most reliable long-term investment for a classic Defender.
