If you own or are considering buying a 1979 Rolls-Royce Silver Spirit, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to tyres: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating. With an average mileage of 81,709 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Tyres — 0.9% of failures
Tyres issues account for 0.9% of MOT failures on 1979 Rolls-Royce Silver Spirit models. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.
Body, chassis, structure — 0.9% of failures
Body, chassis, structure issues account for 0.9% of MOT failures on 1979 Rolls-Royce Silver Spirit 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.
Brakes — 0.9% of failures
Brakes issues account for 0.9% of MOT failures on 1979 Rolls-Royce Silver Spirit models. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
