Pretty good deal for the kid! I spent my middle school and part of my high school weekends helping my stepdad do repairs to our family cars and house. It sucked at the time dedicating my weekends to doing work, but looking back I can't imagine how lost I would be as an adult without this knowledge. This kid will probably benefit more from the knowledge of building that motor than he will with the kickass notch his dad got him. Good to see this kind of stuff still happening!
