Another vote for rebuilt maybe having weird issues. The problem for us is you just don’t know.
Flood damage is a big one, which might mean nothing, or might mean the car is going to be a nightmare - electrical problems, engine corrosion, body rot, musty feet smell that shows up later...it just depends. There are quite a few flood damaged vehicles from recently flooded areas that populate out to other states, so worth investigating the vehicle’s history thoroughly.
Also, I don’t trust Carfax/similar history tools completely- rebuilt or not. We have a car right now with a clean history. Guess what? It goes up on the mechanic’s lift for tire noise. Turns out some object punched through the front undercarriage protector panel and bent some massive bracket that holds the front wheel straight. Luckily, the mechanic is a friend and bent it back, but most would not have touched it. (We had suspicions - the front tow bracket had marks in the paint, suggesting it was hauled out of a ditch or onto a flatbed - we bought it anyway and am happy in this one case.)
