If you own or are considering buying a 1997 Cadillac Deville, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to suspension: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side.

Suspension — 29.0% of failures

Body, chassis, structure — 6.5% of failures

Body, chassis, structure issues account for 6.5% of MOT failures on 1997 Cadillac Deville 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.

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).
