They’re all old, high mileage vehicles. With that said, pick the one in best mechanical shape after a professional mechanic checks out the car, before purchase.
If the engine or transmission needs any major work (>$1000), just walk.
I think they’re all overpriced but try bargaining hard.
The red Accord seems to be resprayed so check that car closely for any hidden damage.
Good luck.
I would prefer the 4 cylinder for Automatic Accords.
Forget about the first one. That generation had a particularly weak automatic transmission and the V6 wears it out even more. The second one is overpriced. The third one seems better but is a little high on price.
I have a mechanic check them out to see which ones in better shape. Make sure to get your hands on service records if you can. My order would be #3>#2>#1
The 03 Accord you posted has a ton of miles and is overpriced like made. I would look into private party. The 1998-2005 Accords have HORRIBLE automatic transmissions so unless you are fine with paying double what the car is worth on a new transmission, look into something newer or a manual.
Do some research,

Plenty of them on craigslist for cheaper

Honda accords don't go for much money anyway. Get one that is in good condition because chances are that it will be a good deal. I think of those 3 are all old and beat up.
