Going CRAZY

OK, well here is the final verdict. (started a new thread cause the old one was dragged out) The '95 GT is set at 5800. Took it to a trusted shop and pulled 3 codes. One was a bad o2 sencor wich is making the CEL light come on and off now, two other previous codes were fuel pump relay dissconnect, and something about the ignition. I asked the man at the dealer and he said the fuel code was from when they installed a 'donut' in the tank so noone could siphen gas...??? Anyone heard of that? Anyway, the guy running the tests said the car looked well taken care of and stuff, still had origional plugs and wires but besides that. The dealer is offering a 3yr 36k warrenty for 1k extra.. SO... thats 6800 for a 95 GT loaded, 5spd with 84k, bone stock with a 36k warrenty.. Should I keep looking?

If I could come to terms and sell my Jeep, then I would have the thousand to spare for a warrenty and performance parts, but I need the warrenty more right now cause if ANYTHING went wrong im sitting with a dead horse.. ...heh..heh... :damnit: but supposidly the warrenty is good for the engine, tranny, axles, seals and gaskets, steering, electrical, AC, suspension, part of the brakes and cooling. So I really want this car but im still in school and got the parting with the first car blues and im just hesitent to spend the money even though I can probaly make it back if I work alot. Hope i'm not getting too annoying.. but seriously thanks for every reply guys.
