I changed the spark plugs on the driver side of my trailblazer suv. I needed the passenger side spark plugs changed as well, but it was more time consuming for me. Boncraft Autoworks was able to finish my job for a real cheap price. On another note, I didnt receive a courtesy call saying my vehicle was ready, instead I had to call and find out. No biggie. Just a small improvement. Looks like a new small business. I will say good job overall.
