The 1999 Vauxhall Monterey's 70.9% first-time pass rate falls well short of the UK average by over 9 percentage points, signalling reliability concerns for a vehicle now a quarter-century old. Nearly a quarter of these cars (23.8%) have recorded dangerous defects during MOT testing, which is a meaningful safety flag for any potential buyer.

These Montereys average just under 100,000 miles, which is reasonable for their age, but the real worry is the 3.57 average failures and 20.3 advisories per vehicle—suggesting widespread wear and deteriorating components rather than isolated problems. Before committing to purchase, have a full pre-purchase inspection completed by a mechanic familiar with this model, as the high failure pattern indicates systemic issues beyond routine maintenance.

We have limited data for the 1999 Vauxhall Monterey — 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.
