Hello, Aleksey! I bought your tutorial; so far I have watched about 65% of the lectures. Before purchasing your auto diagnostic courses, I had my doubts as to whether I should spend my money on it. Because at the time I thought I knew everything anyway, and if not everything – at least 85%; so what new things could I draw out of your lectures? And though I haven’t yet watched to the end, I have realized that I knew nothing at all about how the car, and particularly the engine, is designed and works. Well, of course, I knew something, but it was so little as compared to what your lectures have given me.
Thank you very much for your tremendous work and patience! Wishing you all the very best!
