✓Check the massive 21-inch alloy wheels for curbing; replacement tyres of this size are very expensive.
✓Listen for a whining noise from the rear differential or transfer case, indicating impending bearing failure.
✓On the 3.0d V6 diesel, verify the service history meticulously; oil dilution and DPF issues can occur if not driven on long runs.
✓Test the heavily contoured sports seats for full electrical adjustment, as the seat motors can occasionally fail.
✓Inspect the dashboard for any signs of the material bubbling or cracking under the windscreen in direct sunlight.
✓Check the brakes for judder; the heavy vehicle is very hard on brake discs, requiring frequent replacements.
