Titles and Race Cars

So what everyone is saying that every car racing in NHRA has a title? I'm not trying to be a smart @#$ here but if I had the coin to buy say an old Pro Stock car to run in comp it will have a title? I agree, it is nice to have something official no matter if it's a race car, passenger car, or trailer but I don't believe every race vehicle has one.
I do understand no one wants to spend their hard earned money for something that might not be legit that might be more of a hassel than it's worth.
