Hi Larry I work for a company founded by a automotive teacher who had exactly the same situation as you now. He began developing self-study programs in 1991 to release his own time for practical exercises. Today, almost all automotive schools in Finland use these products. We've also translated some in English, maybe you should test those. Our company name is Prodiags Ltd and our web site is an online store where products are presented in more detail. We would love to hear your opinion about our products.
