I find that your program is a great tool for those of us that love to tinker, with cars. The program has been super in helping me fix some of my soldiers cars and trucks that normally would have cost them an arm and leg. We have been able to purchase an inexpensive hand held scanner, and along with ALLDATA, have actually fixed things they were told would either be unrepairable or would be more cost effective to purchase another car. The cost of your program is pennies on the dollar compared to the repair cost on our autos. Once again thanks for the program. –Mark P.
