I was trading in my 5.7 2011 for a HA, until I was offered an SRT test drive and changed my order. Another $15k and you have one of the most powerful SUVs in the world, in the league of $130k plus vehicles. Gas mileage is much better than you probably expect, with 25+ cruising in ECO mode.
The main additional per mile expense is in tires and brakes, which must be replaced much more frequently.
Still, once you drive an SRT it's all over for the reasonable part of your brain. Even my fiscally conservative wife said, "Wow...maybe we should get this instead" after our first test drive.
So start S
