I commute 80 miles per day all highway 65-70 mph so mileage is a big factor. I can't find one solid reason not to buy a new v6 other then it's not a v8. My concern is I will regret not getting the v8 (cause I'm old and old school) but then will kick my own arse when all I do is drive the car back and forth to work daily and have no real reason to have a v8. Would a set of tall gears 2.73's on the automatic bring the 5.0 into v6 mileage territory? My understanding the 30mpg on the v6 is with these tall gears.
