if the carfax report got cleared up instantly then i see no reason to worry but like someone said previously you are probably better off waiting for the perfect one to come along, so you never have the thought at the back of your head that it could of been a tampered ODO X or a lemon of any sort.

I waited 2 years before i bought mine... craigslist and autotrader everyday, until one day i was just doing a drive by and found my X in the lot... it was never posted online but checked out clean!
