Bmw 116i 1 series m-sport, m preformance package

Alkantara seats M preformance package 4 cylinder twin turbo engine Automatic Apple and android car play Amazing speakers No cosmetic damage Car has 1 mechanical issue, there is a knocking sound from the engine, not timing chain, took it to the mechanics and got quoted 1000€ too fix it, im moving abroad in 3 weeks so doesn’t make sense for me to fix it, hence the good price. Car was bought brand new by a woman, and she kept it very good up untill 120 000km, i bought it and its on 150 000km now. Did diagnosis on car at mechanics 2 weeks ago and no problems except for that knocking sound.
