1999 Rover 623 2.3L Petrol · T46 LBC

The latest MOT test conducted on 6 March 2026 resulted in a pass with no defects recorded. Reviewing the history back to January 2022, the vehicle has maintained a remarkably stable maintenance trend, passing five consecutive annual tests without a single recorded failure or advisory. This is an uncommon level of consistency for a vehicle of this vintage and suggests that the car has been subject to a rigorous regime of preventative maintenance or has been kept in a highly sheltered environment. With a recorded mileage of 103,507 miles over a twenty-seven year period, the vehicle has averaged approximately 3,834 miles per year. This is considered very low usage for its age. While this implies less mechanical wear on the engine internals and drivetrain, low-mileage vehicles often suffer from issues related to prolonged periods of standing. The primary concern shifts from wear-and-tear to the degradation of components that perish over time regardless of distance travelled. Given the clean MOT record, a physical inspection should focus on age-related deterioration. The buyer must carefully examine all tyre sidewalls for signs of perishing or hairline cracking, as rubber compounds harden and lose grip over time even if the tread remains deep. Particular attention should be paid to the braking system; check for binding calipers or significant surface corrosion on the brake discs, which often occurs when a vehicle is not driven frequently. During the test drive, listen for any suspension clunks or knocks that may indicate perished rubber bushes or failing coil springs. Finally, it is essential to verify the service history to ensure that fluids have been changed based on time intervals rather than mileage. Engine oil, coolant, and brake fluid degrade chemically over time and can lead to internal corrosion or reduced braking efficiency if neglected. The health of the 12V battery should be tested, as low-use vehicles are prone to deep discharge cycles that shorten battery life. A thorough inspection of the sills and wheel arches for structural corrosion is also advised, as the absence of MOT advisories does not always rule out early-stage oxidation that has not yet reached a critical safety threshold.
