✓Check the steering for a "notchy" or "sticky" feeling, especially when warm, which indicates a failing electric power steering column
✓Inspect the rear coil springs closely, as the bottom coils frequently snap on UK roads
✓Verify the operation of the cup holders and the condition of the soft-top rear window seal
