Think the Ecoboost is going to surprise a lot of people at just how well it will perform.
As a daily i cant see an issue having one, and hopefully might once the hype drops off.
V8 is real nice but cant justify the extra $20000, fuel economy, and ability to use that sort of horsepower in a daily situation.
Of course if the costs aren't an option, than why not.
Think of how much you save over an AMG Merc.
