I'd like to ask a question about a Carfax report, but from searching existing questions it looks like the general consensus is that this community is strictly dedicated to vehicle maintenance/repair. Where would this question be on topic?
To be very honest with you, I don't think there is an SE community which would tackle this kind of question. You can always ask your question of this nature in our chat room called The Pitstop. There it is a lot more free form and we can talk about such things.
