Very well maintained X3 fully loaded and woman driven. latest adds: breaks pads/disks, shocks, android/carplay system, rear view camera. All is working on the car.
For a connaisseur/mechanic, and as explained to us, the engine was verified and compression on all cylinders is good within specs (no issues with the engine). but it seems our X3 has a VANOS issue (as explained to us). repair cost is estimated to 3000$ which explains the reduced price.
