Peter: I wouldn't care for diesel simply because I'd be afraid of going outside on one of these cold northeast mornings and cranking my car, only to find out it wont start because my fuel has turned to Jello. Besides, who's to say a well-maintained 4.5 can't get 500k miles? The main reason they don't is because of stuff like my car - runs great, has (probably terminal if not fixed quite soon) RUST! 68 likes his 350, I like my 4.5. You should like your 4.5 too, Peter... Oterwise, find someone willing to "Suffer" through 15MPG! (HELL I wish my 4.5 got 12MPG! I'd be thrilled with 15! 50% better milage! )
