ok this saturday i am picking it up its an f-150 xlt lariet w/ a manual transmission, a 5.0L engine, it has 100k on it, and its got a new paint job. its an 87' and its in pretty good shape. I am getting it for $1500. its going to be my first truck and since everybody thinks i am going to get in a reck the first week after i get my lincends i didn't want to spend a whole lot of money on a truck. i was just wondering if you think it was a smart thing to do and if you think i got a good price on it i need a device for it that will save some gas and was considering flow masters. What do you think about that? and if i get it how much gas will it save?
