I'm looking at purchasing a 2002 Landrover Discovery SE7. There's a Service Engine Light on so on test drive I took it to Auto Zone these codes came up P0300,P0304,P0306,P1413, P1668,P0455.... Should I buy this vehicle? There's also a inconsistent rattling noise underneath when I go over a bump like something is loose and the engine sounds like a belt is dry or tight bcuz it squeaks when running.

 

I should have run as far as possible when I saw my land rover advise run till you cant run any longer.

 

buy it for 1K or less

 

Thanks!
