I bought my 93 f150 in 1997 with 40,000 miles, i now got 217,000 and still runs like new! This truck is very Reliable as long as you keep up to date and well maintained. For being an old hunk of truck, its a very nice ride (if you don't mind a little noise on the side) and hauls great. This truck has never let me down. I've had a 07 Chevy 1500 and Ram 1500 (almost NEW work trucks) with less than 200 miles, both tranny's blew at around 124- 135,000 miles, the rams engine even went at 150,000.("these trucks were just for driving state to state with little or no cargo") That leaves me to say that the 93 f150 is more reliable than most newer models trucks.
Better fuel economy, better find ways to improve your Mpg!
