2004 Lexus RX300 3.0L Petrol · JC54 NEV

The Lexus RX300 presents as roadworthy following its most recent MOT pass on 4 February 2026 at 136,869 miles, with no defects recorded. The maintenance trend is stable. The vehicle cleared its test first time after a failed attempt on 8 January 2026 at 136,840 miles where the tester logged no defects, indicating the earlier failure likely stemmed from administrative or non-mechanical grounds rather than wear. Prior to that, the 3 January 2025 pass at 124,208 miles and the 5 January 2024 pass at 110,187 miles both recorded clean sheets. Annual mileage sits at a modest average of roughly 6,200 miles across the vehicle's 22-year life, with the record showing 110,187 miles in January 2024, 124,208 by January 2025, and 136,869 by February 2026. That equates to about 14,000 miles added in the last two years, a mild uplift on the long-term average but no cause for concern on a petrol V6 SUV. The two failures in December 2024 and January 2026 both carry zero recorded defects, so the data gives no evidence of neglected consumables or deferred repairs; the history is sparse and clean. A buyer should still commission an independent inspection of the suspension bushes, front coil springs, and brake disc thickness given the vehicle's age and the RX300's known propensity for rear subframe corrosion. The MOT record flags no structural integrity issues or exhaust emissions faults, yet a 2004 chassis can hide underbody rust unseen in a test lane. Verify the 8 January 2026 failure reason with DVSA, as a no-defect fail is unusual and may point to a documentation error or an abandoned retest rather than a mechanical fault. Check the service history for evidence of transmission fluid changes on the automatic gearbox and confirm tyre ages, since the record notes no advisory wear. The previous owners appear to have kept the car to a sensible annual distance and cleared every pass with no advisories, which suggests basic upkeep was maintained even if the two zero-defect failures remain unexplained.
