Ugh... you dont' get it do you? CarFax doesn't tell you enough.
The experiment I conducted and the experiment Navigator conducted proves that. Trust a $15 piece of paper if you wish, but I am telling you it isn't enough and is actually a waste of money in most cases. Is it better than nothing? That depends entire on how much information is available and how much of it is current and accurate.
Why don't I do it? You have to ask? Do you think it's wise to waste $15 on something that may or may not tell you what you need? Might as well spend that $15 on a fortune teller!
The horse is dead.
