Dont know were im going in the hobbie anymore:

Genetic. For many of us we are born with a passion. For some others, a car hobby is short lived. Then on to another hobby. Those were not born with that passion. Sometimes life gets in the way, BUT if we have a true passion it follows us all our lives. For some, it catches us later in life. I swear I have seen some people that were born with ability to rebuild and tune a carb! ( NOT me)... GENETIC ....not learned.
Passion for cars is like passion for horses. It is in the blood. Genetic. I am lucky or cursed??. I have passion for Mopars and Quarter Horses. NOT Chevys or Arabians. Some others have that passion for those.
I will own both till I either die or can not take care of them any loner. A passion. Maybe it is crazy maybe???
