We bought our Fiesta a little over 2 weeks ago. We immediately took it on a 2000 mile trip. I'm 6/4", and I was comfortable even after driving for hours. Not much legroom in the back, but plenty up front. We were amazed about how quiet it was, and how good the fit and finish was. When you close the doors, you get a nice satisfying solid sound, like it's well built. It has several options normally only found on bigger cars, like heated leather seats, heated mirrors, sync, a soft-touch dash, and an auto-dimming mirror. So, after 2 weeks, and 2600 miles, we have found a lot to like about it, and I would highly recommend it.
Sync -- Traffic, weather, directions, business searches, ipod control. Ride and handling. Handles almost like a sports car. The A/C will freeze you out on a 100 degree day. Blind spot mirrors - There will never be a hidden car again.
Dual clutch automatic can be a bit akward at first, like it's searching for the right gear. Instrument panel lights are always on. When the sun sets, you've got to remember that you don't have your lights on already. No center arm-rest.
