I bought a car, private sale and the car won't pass safety inspection in NH

Man that really sux big time. Wish I had some solution for you but based on what you described, it sounds like it would be a labor of love for someone with loads of cash, time and in top physical shape to do the work. Maybe one of your buddies could intervene and get your plight on one of those consumer advocate segments on the news. Nobody likes hearing about someone in your shoes being taken advantage of like this. Wishing you the best and hoping karma is a b!tch for the other guy…
