Buying one or MOT due? Check these

  • Indicator side repeaters 5.1× typical
    Walk around with the lights on: bulb failures are the easiest MOT fails to avoid.
  • Tyre damage & cracking 1.5× typical
    Look for cuts, bulges and cracking on both sidewalls of every tyre.
  • Suspension arm bushes 2.1× typical
    Listen for knocks over speed bumps and feel for wandering or vague steering.
  • Headlight bulbs & units 1.5× typical
    Check dipped and main beam on both sides.
  • Engine warning light 1.9× typical
    The engine warning light should come on with the ignition and go out once the engine starts. If it stays on, get the fault codes read before you buy.
  • Headlight aim
    Park facing a wall at night: both dipped beams should sit level and dip to the left.
