Rust is a major concern, particularly in the sills, wheel arches, and around the windscreen and rear window. Engine components can wear, especially if the vehicle has been used for spirited driving. Suspension components, particularly the shocks and springs, can degrade over time. Check the condition of the trim and originality of the HDT components and badging.
WOF tips
Brakes are critical; inspect brake lines, pads, and rotors thoroughly. Steering play should be minimal. All lights must be functional. Tyre condition must meet WOF standards. Rust affecting structural integrity will result in a failure. Exhaust emissions will be checked.
