2007 Mercedes Viano 3.0L Diesel · GV57 RXB

The Mercedes Viano remains roadworthy, but the MOT history reveals a persistent trend of deferred maintenance regarding the rear axle components. The most recent test in February 2026 at 124,461 miles flagged corroded on both rear brake pipes and slight wear on the rear anti-roll bar bushes. While the vehicle consistently passes, the recurring nature of these faults across the last five years suggests that repairs are only being undertaken when necessary to pass the inspection rather than addressing the root cause of degradation proactively. The vehicle shows a very consistent usage pattern, averaging approximately 6,500 miles per year over its 19-year life. Between March 2022 at 98,203 miles and February 2026 at 124,461 miles, the vehicle covered 26,258 miles, maintaining a steady rate of travel. This low mileage relative to the age limits mechanical wear on the drivetrain, but the age of the vehicle means that rubber components and metal lines are naturally susceptible to environmental corrosion regardless of the distance travelled. A buyer must prioritise a thorough physical inspection of the rear braking system and suspension. The tester has noted corroded brake pipes since 2022, and pitted discs were flagged in 2025, indicating the rear hydraulic assembly is reaching the end of its effective life. Furthermore, the repeated mentions of worn anti-roll bar bushes, linkages, and shock absorber bushes across multiple years indicate the rear suspension geometry is deteriorating. The buyer should check for excessive play in these components and ensure that the grease mentioned on the brake pipes is not merely masking deep structural corrosion of the metal lines.
