Better fuel mileage would be great and I'm content with the power of my current truck. I wouldn't buy a new truck just to get more power or better fuel mileage.
What to me is the most impressive about the newer trucks is the longevity that they have.
I'm sitting at about 137,000 miles and my truck still runs like new, doesn't use a drop of oil and the the maintenance cost are half what they used to be while having twice the HP and better fuel mileage than they got in the old days.
Its all relevant but I can't comprehend $70,000.00 for a new pickup truck.
