Vehicle Value Check
Vehicle Value Check
A typical Land Rover Defender 130 D300 of relevant age (2022-present) currently holds a UK market value of approximately £60,000-£85,000+ [THIRD-PARTY - Auto Trader / Cazoo market observations]. At this premium value band, a reconditioned or rebuilt engine replacement is a small fraction of the vehicle's worth and easily justifies the investment to preserve performance and resale value.
