The 1999 Ssangyong Musso has a first-time MOT pass rate of 68.2%, which is 11.8 percentage points below the UK average of 80%, signalling below-average reliability for its age. A quarter of these vehicles (24.1%) have recorded dangerous defects at some point, which is a genuine concern for a prospective buyer and suggests structural or safety issues warrant careful pre-purchase inspection.

These Mussos are running at a median mileage of 91,236 miles—reasonable for a 25-year-old vehicle—but they're accumulating an average of 2.58 failures and 10.3 advisories per MOT, indicating persistent wear across multiple systems rather than isolated problems. Before committing to one, have a trusted mechanic conduct a full inspection, particularly focusing on the chassis, braking system, and steering components where dangerous defects have been flagged.

We have limited data for the 1999 Ssangyong Musso — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
