I believe that I-CAR has worked well for the industry. My thoughts are, why reinvent the wheel. If they're doing a good job we should continue to use them. I teach collision repair and use their curriculum. I recently attended a Shark Measuring class, which was good, so you could check with your vendors for additional training. As far as repair info., our school just purchased AllData's Collision Connect. To watch a demo video you can visit
