Have a 2005 GMC Pick-Up that was doing all sorts of strange things just before it took a trip to the great beyond. I did multiple web searches and heard every bad story (and nothing) good about the problems. Everything from Dealerships not being able to find or correct the problems to other shops charging over $1,000 only to say that they don't have any idea what the problem was after changing out a lot of unnecessary parts. After finding several broken wire grounding problems, the Main problem problem was traced to the Main Brain (computer) which had gotten shorted out because of the grounding problems. They replaced that 1 (one) part and I was back up and running. Have taken other auto's to Snellville Auto Center and all have been fixed quickly and at a fair price. I will continue to take my auto's there and will continue to tell others about their great service. Eric Crawford
