It's a rebuilt title.
As it's flood damaged, you should ask for a mechanical assesment to know of any damage. If they do not disclose glaring defects or poblems they would have to have noticed in comon sense (mold comes to mind), you can sue for breach of contract. Such things as the engine and transmission will have been drained, dried, and inspected before you can get a new title. In this case it's about 500.00 worth of work by a mechanic you trust and another 100.00 or so to get a state inspector to check the car out for a new title. They're portraying it as running and functioning fine. confirm that in email. If it is, then that means the fluids where drained, the car was left to dry, and then refilled. For a small drive like 200-300 miles from chicago to NY, that will do until you have your mechanic look at it.
The instructions for obtaining a brand new title for this car, as well as the inspection critieria and required forms for New York state can all be found

Your in luck because NY is one of the few states that will re-title a flood damaged car. Florida won't. In fact, it's the only damage they won't retitle in florida. Everything else is fair game, which makes it a haven for classic cars and good cars on the cheap. They're all rebuilt
I would also email some of the people who left positive feedback and ask them if thet're still happy.
*edit*
I'm telling you to get in writting that it runs because i buy cars that don't run. Bent axels, frames, accident cars, etc. If it's really a car with lite flood damage, it will need some work but mostly just needs an inspection of the engine and tranny to check for water damage to the components. rebuilding a tranny is a 300.00 job for basic servive and something i won't even do myself. Your primary concern in buying a flood title is the powertrain. If that's in good shape then your good. no other area will costs you as much to deal with as that.
