2003 Mercedes-Benz C 1.8L Petrol · FM03 LLJ

The 2003 Mercedes-Benz C remains roadworthy as of the most recent test on 22 January 2026 at 117,607 miles, where the tester recorded a pass with no defects. The maintenance trend is stable. The vehicle shows a consistent pattern of passing only after an initial failure on the preceding day, with the 16 January 2026 failure at 117,539 miles and the 16 January 2025 failure at 112,269 miles both listing no defects. This suggests administrative or presentation issues at the first attempt rather than mechanical faults, and no worsening condition appears in the record. Recorded mileage sits at 117,607 against an age of roughly 23 years, equating to about 5,113 miles per year. The car covered only 5,328 miles between the January 2024 test at 108,083 miles and the January 2025 pass at 112,279 miles, then 5,328 miles again to the January 2026 pass. Such low annual use implies light running but also probable long stationary periods, which can encourage corrosion and perished rubber components despite the clean test sheet. The DVSA data is sparse, with no advisories or defects logged on any pass or failure. A buyer should still commission an in-person inspection of suspension bushes, coil springs, and brake discs given the vehicle's age and low-use profile. Standing time accelerates degradation of flexible joints and can cause binding calipers that a short MOT drive may not expose. The repeated next-day pass after failure points to clerical rejection rather than rectification, so verify the VIN and test certificate directly with DVSA. Structural integrity and underbody corrosion warrant particular attention on a 2003 chassis. The absence of advisories across five tests does not rule out early-stage rust in sills or subframes. A independent ramp inspection remains prudent before purchase.
