Everyone justifys their purchase by saying they don’t notice a huge drop off in performance. There’s a massive gap between the 6.2 vs 3.0. The 3.0 is a cool engine buts it’s deff sluggish. Heck I drove all 3 and the 5.3 was more peppy than the 3.0. That mpg is on point though. The question is literally smile per gallon vs Mile per gallon, what do you prefer?
