Salvage and reconstructed are two completely different things.
salvage title = severe damage, usually exceeding 75% of the car's value
reconstructed = car that has been rebuilt and is considered roadworthy, but used to be salvage/junk- has to pass inspection in most states

What is a rebuilt title or a salvage title??
To the OP- the seller should disclose that the car has a reconstructed title. Although a reconstructed car typically has to pass inspection to be considered roadworthy and get that type of title, inspections don't catch everything, and there's no way to know what was rebuilt unless you're able to find the history of the car. Get receipts/crash report from the seller.
In some places, an engine theft or theft in general can cause a car to get a salvage title- in those cases, replacing the stolen parts or just recovering the car would give it a reconstructed title. I would personally have no problem buying a car like that if I knew the builder. A guy at work just bought a reconstructed title S4 from his brother-in-law in NYC- the car was recovered intact 3 weeks after a theft. No mechanical problems.
You really just have to know what happened to the car. If you're comfortable with it as is, stick with it- but you can get clean EK hatches for not too much more. By the way, I don't think there was a 6th gen hatch that came with VTEC from the factory in the US. Consider that.
