I guess alot of it is that if you have to worry about fueling the car you probably shouldn't be getting it. That said, I originally wanted a 3.0 but with the left over '07 4.8s there were some great deals but I couldn't come to an agreement with the dealer. Some here got even better deals on the 4.8s than I got on my 3.0. That said, I am pleased with the 3.0 as it so far has fit my needs. Btw, I do not intend to tow anything, ever.
