If you own or are considering buying a 1992 Mercedes 609, be prepared for above-average maintenance costs. Before your MOT, pay particular attention to steering: Check for excessive steering wheel play (more than a few inches of free movement). Listen for whining from the power steering pump.

Steering — 14.3% of failures
Steering issues account for 14.3% of MOT failures on 1992 Mercedes 609 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.
Brakes — 10.7% of failures
Brakes issues account for 10.7% of MOT failures on 1992 Mercedes 609 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).
Body, Structure and General Items — 3.6% of failures
Body, Structure and General Items issues account for 3.6% of MOT failures on 1992 Mercedes 609 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.
