WOF tips
When getting a WOF, pay close attention to rust, especially near structural areas; ensure all lights are functioning correctly, as this is a common failure point in older vehicles. Check the condition of the tyres, brakes (pads, rotors, and lines), steering components (play in the steering wheel), and suspension (excessive movement or worn bushes). Exhaust systems are notorious for corrosion, so ensure its integrity and emissions meet standards.
