plus i figure when i sell it someday to start a new project, i could represent the paper work that it was professionally installed. some people are really picky and will not be satisfied that a 16 year old put a new engine into the car. it is mostly small mindedness, but that is something i will have to live with. face it, old people and authority figures suck, they impose on all of our fun and possible learning experiences. a little hypocritical i would say.
