Off topic but FYI since you asked:
You can buy a salvage vehicle in NY get it registered and drive it on the road.You can get liability insurance but I am unsure if you can get collision insurance on a salvage title vehicle if the insurance carrier is aware of the title status. The reason is simple.
Here collision/comprehensive insurance policies are based on the Actual Cash Value of the car (ACV). Determining the value based on condition, age, options is none too difficult but the value of a vehicle that has been damaged to the point of 75% of it's ACV and put back together is the problem.
It becomes branded as a way of protecting the unsuspecting buying public from folks that buy or retain ownership to these vehicles, meet the standard of rebuilding with no stolen parts and passing a standard NYS safety inspection.
They don't want people to pass them off as anything other than what they are, cars that had enough damage to be totaled.
Selling a car with a salvage title or any vehicle that has had damage that meets or exceeds 75% of it's retail value and not disclosing that to the buyer prior to the sale is a crime in NY and that law is for all sellers, dealers and private individual sales.
Bearing that in mind salvage buyers from states that do not have such laws in place, such as Mississippi are willing to pay more for a salvage vehicle than most bidders based in NY and consequently feel they are getting a good deal when they do so since they can erase the salvage history if they want. Doing so could raise the market fetching price of the car to that of a car that did not suffer such a consequence, possibly by thousands of dollars.
Buying a salvage car with damage that the buyer feels they can remedy within their budget makes it a good buying opportunity, like for example, this fellow here has done.
I'd buy a salvage NSX for the right price too if I could. I'd make a track car out of it and never register it at all.
