For sure
I think we even have a thread on here that bemoans the poor results for both. The email contact only Carfax is the epitomy of screw you customer service. Just think of all the non reported accidents that people who work on cars themselves do not report. I think the realization of how bad they suck is a big reason for all the money they now spend on advertising. Of course there is no way to get info on unreported problems so that is a big reason the expense is a waste of money. A better solution is paying $$$ to a trusted mechanic to look for signs of repairs or other hidden problems.
