My Landcruiser blew a head gasket and my mechanic told me that it's dead. He's showing interest in buying it because he found an engine to put in it. The car was garage kept, so there's no rust, a few little scratches and dings. The engine only had 72k miles on it. I just put 4 new tires on it, has runners, grille guard, moon roof, roof rack and CD player. Since the engine is dead, how much is the car worth. He's offering $500-$1000 for it. Is it worth more than that?
