Query: Alldata

Simply put, Alldata sucks. I'm an ASE Master Technician. Alldata has given me fits in the past. I won't use it. If you want the best and don't like wasting time, in my experience (10 + yrs.), get Mitchell repair manuals. I just clicked on this site to see why an employer would buy it as mine did...you get what you pay for.
