Reported by owners, mechanics and buying guides for this model and age. Check which engine the car has, as some apply to one engine only.

  • Clunky 2-Tronic automatic
    2-Tronic / x-shift automatic

    The optional 2-Tronic is an automated manual, not a true automatic. It can feel jerky and owners rate it poorly.

    At the viewing: Drive it in traffic and pull away several times. Make sure you can live with how it changes gear.
