If you own or are considering buying a 1987 Renault R21, budget for potential repairs before each MOT. 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 91,875 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Tyres — 2.0% of failures
Tyres issues account for 2.0% of MOT failures on 1987 Renault R21 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.
Visibility — 2.0% of failures
Visibility issues account for 2.0% of MOT failures on 1987 Renault R21 models. Visibility failures relate to the windscreen, wipers, washers, mirrors, and view-obstructing damage. Cracks in the windscreen swept area, ineffective wipers, or empty washer bottles are common causes. Typical repair costs: £10–300. Pre-MOT check: Check the windscreen for chips and cracks — damage larger than 10mm in the driver's swept area or 40mm elsewhere will fail. Test washers and wipers. Ensure both door mirrors are intact and adjustable.
Body, chassis, structure — 2.0% of failures
Body, chassis, structure issues account for 2.0% of MOT failures on 1987 Renault R21 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.
