About This Data
The 1975 Alfa Romeo Montreal has an MOT pass rate of 76.9% based on 65 tests — well above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 55,104 miles on the odometer. With a 23.1% failure rate, the 1975 Montreal is rated as "Excellent" for MOT reliability.
If you own or are considering buying a 1975 Alfa Romeo Montreal, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to body, chassis, structure: Inspect sills, wheel arches, door bottoms, and the chassis for rust. Surface rust is acceptable but structural corrosion or holes will fail. Check that all doors, bonnet, and boot close securely. At 55,104 average miles, these vehicles are in the mid-range where component wear starts to become a factor.
Body, chassis, structure — 1.5% of failures
Body, chassis, structure issues account for 1.5% of MOT failures on 1975 Alfa Romeo Montreal models. Body and structure failures include excessive corrosion, sharp edges, loose panels, and damage to the vehicle frame. Rust is the primary concern, especially on older vehicles or those exposed to road salt. Typical repair costs: £100–500+. Pre-MOT check: Inspect sills, wheel arches, door bottoms, and the chassis for rust. Surface rust is acceptable but structural corrosion or holes will fail. Check that all doors, bonnet, and boot close securely.
Noise, emissions and leaks — 1.5% of failures
Noise, emissions and leaks issues account for 1.5% of MOT failures on 1975 Alfa Romeo Montreal models. Emissions failures occur when exhaust gases exceed legal limits for carbon monoxide (CO), hydrocarbons (HC), or particulate matter (diesel). Common causes include faulty oxygen sensors, clogged catalytic converters, or DPF issues on diesel vehicles. Typical repair costs: £100–1,000+. Pre-MOT check: If the engine management light is on, get it diagnosed before the MOT. For diesel cars, ensure the DPF has completed a regeneration cycle. Regular servicing and using premium fuel before the test can help.
Steering — 1.5% of failures
Steering issues account for 1.5% of MOT failures on 1975 Alfa Romeo Montreal models. Steering failures include excessive play in the steering wheel, leaking power steering fluid, worn track rod ends, and damaged steering rack. These affect vehicle control and are closely related to suspension wear. Typical repair costs: £150–600. Pre-MOT check: Check for excessive steering wheel play (more than a few inches of free movement). Listen for whining from the power steering pump. Look for fluid leaks under the car near the front wheels.
