Boy me and the old 01 V10 are really falling behind here! Fixing to be changing jobs, so a Diesel will be in my future as well, for the added fuel mileage. My V10 gets about 14.5-15 on the highway, and I`m told the 6.7 will do 20+. But we are for sure still going to be together a while, since it`s only got 43,450 miles on it.....
