Moderate sample. 441 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.
The 1997 Vauxhall Monterey passes its MOT first time in 72% of cases, which is notably below the UK average of 80%, and nearly a quarter of these vehicles have recorded dangerous defects at some point—a real concern for a 27-year-old vehicle. Petrol and diesel versions perform similarly (71% and 73% pass rates respectively), so fuel type won't be your deciding factor here.
These Montereys are averaging around 123,000 miles, which is reasonable for their age, but they're racking up 3.3 failures and 17.4 advisories per test on average—pointing to cumulative wear across multiple systems rather than one dominant problem. If you're considering one, budget for regular remedial work and get a pre-purchase inspection focused on brakes, suspension, and structural corrosion, since the dangerous-defect rate suggests these areas deteriorate significantly over time.
The 1997 Vauxhall Monterey has a below-average first-time pass rate (72% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.
These stats describe 441 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.

Brake pipes, sills and subframes are the key areas on a vehicle this age — structural rust is hard to spot without getting underneath. A mechanic will check all of this before you commit, and give you a concrete basis to negotiate on price.
