You should list it for 2k or best offer, you should be able to get that especially if it is gonna be a project car as the engine will probably be rebuilt anyways, here in the Junk Yard a GSR engine goes for around close to 3k alone. . .

as for the title, that depends why it was salvaged, if it was just like a theft recovery , that that wont matter, but if it was in an accident, then it will depend on how bad. . .

body and paint should not be your concern as whoever is looking to buy it will see it and know that body and paint will be a must. . . other parts are normal wear and tear, but if you fix the little end stuff, you can maximize your sell. . . fix the axle prob and figure out why its burning oil, but then again. . . it was free to you, so what you can get for it how it is, still makes you $ $ $. . .
