Are you going to pick it up yourself? If so, don't sign anything or give anyone any money until you are there to inspect it personally. There are plenty of nasty surprises that can be present, that don't show on Carfax. Someone could've driven it over a curb at high speed, gotten it fixed, traded it in, and that would not show on Carfax.
I'm picky about paint condition, wheel scrapes, chips in the glass...well, pretty much anything cosmetic. Dealers, private sellers, etc. all tend to conveniently leave out the small details either because they don't notice them, or they just want to make the sale and don't consider them to be a factor.
If it were me, I'd find a way to make a personal inspection happen. If it looks good, your trip wasn't wasted. If it's not good, restrict your shopping to local.
