    Why it matches

    N20B20A rebuild service listed specifically for 320i and 420i — same engine as buyer's 420i Gran Coupe 184ps; remanufactured condition, not used/salvage as briefed.

    • Live listing
    • Fitment checked
    • Mileage not stated
    • Damage not stated
    45% match — why?

    Live listing for N20B20A engine rebuild service explicitly referencing 320i/420i; correct engine code and fitment, but listed as 'Remanufactured' rebuild service rather than a used/salvage bare engine as the brief specifies — include for buyer awareness.

    Condition: Remanufactured/rebuilt — this is an engine rebuild service, not a straight used-engine purchase; buyer may need to supply core engine
