I test drove one about 3 years ago and was severely disappointed. Fit and finish were not that great and it was slow and laggy. It had good brakes. That's all I can say for it. Then I went and drove a Taurus SHO. HOLY CRAP!! Not only was it so much nicer, but it was stupid fast. Kind of apples to oranges but I was sold on Ecoboost. I bought a 2010 Flex that was super nice and hauled ass big time with just a tune. I never took it to the track, but I'm sure it was a very low 13 second vehicle. I put on a ton of miles and sold it along with my Titan a year later to get a new 2013 F150 FX4 Ecoboost. With just a tune it ran 13.5@100. It also tows amazing. I am considering selling my 2014 WRX hatch to get another Flex. I would love a SHO, but the 100lb trunk I carry around is easier to load in a hatchback and I don't know if I could get over the ugly factor of the Taurus.
