He must love 318s to want to keep it that bad. Sometimes those pop up like that here, not usually THAT bad, but most 318s are <$400 (carbs and intakes are expensive- and those add up into them too), and the 5.2s are right in that range- usually $550 can buy a 5.2 with all the spaghetti and the lumps of plastic to run it- and not too much more'll buy a running vehicle that doesn't smoke albeit with higher miles.
