Found a guide that helped me understand mechanic pricing

I have always struggled with knowing whether I am paying a fair price for car repairs or getting ripped off. Every time I go to a garage I feel like I am at a disadvantage because I do not know what things should actually cost. A friend shared a link with me that broke down common repair costs and what influences pricing at different workshops. If you are in a similar situation you might want to read more here  because it really opened my eyes to how much variation there is between places. I learned that some workshops charge more simply because of their location rather than the quality of their work. Now I feel more confident asking questions and comparing quotes before committing to anything.
