I had an alternator fail on my GL320. GA replaced and corrected that problem effectively and efficiently. Later the car started shredding serpentine belts. They replaced the tensioner pulley and the belt. it happened two more times. It was eventually determined the alternator pulley was the culprit. They fully refunded the repair costs caused by the bad alt pulley and I didn't even need to ask. It took a few trips in but they always took care of me, the towing, and my transportation needs. That is a level of care and integrity seldom seen today. It is usually a complete waste of time to even ask if a shop will accept responsibility for a mistake, that is not the case at Global Autoworks. I drive from muskegon and pass many shops to get there. I am sold on the service, care and integrity.
