I own a shop and work on vehicles in Alaska. When I was going through my customers and the vehicles that I have worked on to aid me in the decision as to which computer tool to purchase. The ford IDS program or the gmc program. I found in my research that most of my customers owned fords. But my biggest repairs and highest cost to be repaired were chevy's. Fords mostly come in for minor maintenance oil changes ect.. So having this knowledge, I had to buy a Ford.
