Hi, My friend was in a crash a few days ago all that has happened is his bumper, wing, light, hood, maybe radiator are broke... he offered me the car for £100 so i could have the engine and swap it with my citroen saxo 1.1 would it be a quick swap or is there a lot i would have to change and is there any damage that could have been done to the engine in the crash it looks like the engine was un touched by anything but could there be any internal damage?
