These guys are jokes they don't have any idea about the things they are doing
Don't ever go to this place unless you really know what you do. I brought my car there for computer check when there were no major issues, but since i was about to sell it, my buyer wanted a report. First they asked for qar 1000 for computer check and engine check... total crasy but my buyer bargained to qar 500 which is still quite expensive. When i got back the car they give me a report of repairs long enough to write a book and most importantly: when i started driving it, my car was shaking and vibrating like crasy. After bringing the car to another garage i was told that they must have drove it so crazy that they burnt one ignition.
Last advice: stay away from this place they are a bunch of crook.
