I bought a used car recently but discovered that the left rear wheel camber alignment was off, leading to accelerated inner tyre wear. Brought the car to several workshops, including a branded workshop in Loyang, but they either could not find the cause nor fix the issue. Guan Motor Works managed to diagnose that the vehicle had been in an accident before and the previous repair job was not done well. They diligently dismantled the accident area of the car to check on the previous repair job and noticed that the rear axle was slightly bent, left rear boot panel was not reshaped properly causing the left rear lamp cover to be out of alignment. The trunk opening cable was also not attached back to the trunk lock. I am extremely satisfied that they managed to fix all the above-mentioned issues without parts replacement or respraying and the car is pretty much back to original condition. Great workshop with knowledgeable staff, honest pricing and meticulous workmanship!
