We have had our diesel for about 2 months now and still find that the steering takes a bit getting used to. That's really the only con if I had to say. It's just a tad heavy. But whoever is using the cost of gas vs. diesel as a reason to stick with a gasser is probably going out there and buying the cheapest gas they can find on gas buddy. If you are comparing prem gas to the cost of diesel as you should then you will find the diesel is the way to go. We went from averaging 15 miles day to day driving to 22 when we switched.
