Great experience
I was curious about how difficult it woudl be to replace my speed sensor. I did a web search and found an extremely helpful video on the A1 Auto site. After watching the video, I looked up the part, and was also delighted to find a very competitive price. I order it immediately, and it arrived just a few days later. It went in exactly as the video suggested. Overall...very helpful, and a great experience.
