Vehicle with a Salvaged Title, then Rebuilt Title?

Well I went to test drive this 1999 Honda Accord LX from a private party. The owner wasn't there so she left her keys with her teenage son, who showed the car to me. I test drove it, it seemed to run great, engine made no weird sounds, everything was clean, interior, paint & body, and engine components...
It has a "2.3L L4 SMPI VTEC OHC" engine, automatic, 6 inch exhaust tip, Euro tail lights, car alarm with remote start activated, "Type R Racing" decals and a few other small upgrades... 6 cd changer... I am guessing all from the original owner, since the lady I will be getting it from is a Mother... But you never know. Maybe she likes to soup up Hondas with vTec engines and put a baby seat in the backseat. *shrug*

Anyway, KBB is 8.5k for good condition, which this is in, they are selling for 7.9k, which I may be able to talk them down a little bit.
I have a question though -- Anyone here have any precautionary warnings / advice on buying a car with a salvaged, then rebuilt title? It has been verified through DMV, all information about the resalvage gathered from CarFax.com. Everything seems to check out, I am having my friend come with me to look at it again tomorrow afternoon, who knows a lot about cars, and if he says everything is cool, I may get it on the spot.

Anyhue, input would be appreciated.
