I am a car enthusiast.  Driving is a real thrill that never gets old.  It's also a pleasure to work on cars.   I do my own repairs.  I meticulously service all systems (electrical, fuel, cooling, brakes, chassis, body, paint, interior, suspension, and transmission...) one by one, returning them to their glory days.  A bit obsessed with keeping them clean, neat, and running.   No corners are cut in maintaining these cars.  I don't own them, they own me.   
Not all cars made the list.  Too many to keep track...
