First and foremost, I disagree with the fact that you have to pay a fee to use their services. They are secretive about the way this works. Their advertising is extremely deceiving because they ended up charging me without notification.
Second, I used their website one time when I was trying to buy a new car. I did not find it very useful at all. They did not reveal the full accident report of vehicles and they wanted me to pay even more money in order to look at more.
I went with a different website, but little did I know that for four months they continued to charge me every month. This site was made to make money, not help.
