I have used alldata for many years, and loved it. Tried Mitchell hated it was not easy to use. Started using Identifix and its a dream it helps with repair problems does estimates looks up parts with your suppliers price checks. I think the price is a little steep at $180.00 a month I think it could be less expensive. They even order us lunch and had it delivered to our shop. I don't think I could function without Identifix.
