The problem with the salvage title is that you never know how bad the car is, there may not be any damage where as some cars have frame damage. I sure the car didnt only have windsheild damaage. Check the body of the car, it will surely have fillers inside. Knock the side where accident occoured and the back body without accident, you'll find the sound is different. 
Also selling the car like that is a hassale.
If you decide to buy the car have i inspected by a mechanic completely !!!!
There was a guy in sajha who was offering free VIN checks, find that thread. Im sure he will help you out. Have a good one.
