Also the tune can play a lot into MPG depending on how he drives. You can always be more lean on a daily driver than you can on a car that you are going to beat the snot out of, so keep that in mind as well. Just be sure to let him know this in advance

Agreed. We purchased a couple of 4.8 work vans in 2005 for the fuel economy. The advertised mpg was higher with the 4.8 option, so instead of going with the 6.0 liter vans, which were the same price by the way at the time, we opted for fuel economy. BIG mistake. I have to keep my foot in the gas way more to keep the van up to speed, which kills my mileage. Flat ground is ok, but not a lot of that in North Georgia. Lesson learned.
