I'm searching for a good and trusted service that provides car history reports (mainly for MB cars 1990+ models). I heard about these companies recently and I would like to know more about them. I'm going to make a subscription since I have a lot cars that I need to check the history of (accidents, condition, ...). I would also like to know the advantages and disadvantages, any advice are welcome. If anyone here is currently subscribed to one of these services, may I know what kind of information do they supply and what is the fee range?
