I have been learning a lot from a friends dad. He started working on cars when he was around my age and he had to sell his first race car at age 25 when the kids came. Now he is almost fifty and bought back his old race car and the quality of work on the first car is pretty funny when compared to the cars he has built since. One day I'll look back on some of the stuff I did when I was 16 and really have a good laugh.
