420 vs 500
with 62.000 miles on it.
i am wondering if the 5.0L will use much more fule then the 4.2L, or it is very similar.
i know their it is a no brainer when it comes to the mileage, i was wondering how much worse it is on gas. I did not buy the car cuz when i went to see it it was a rust bucket, i did drive it and it does have much more power especialy off the line, mine is a slug off the line especialy when the A/C is on.
the serch is on for a good S500.
