Bought my teen a 2014 Fiesta SFE 5spd with the 1.0, Ecoboost 3 cylinder engine. 12k miles, local trade.
Drove it 700 miles over our Christmas travels.
The little car is fun to drive.
The engine had no issues keeping the car at speed in 5th gear.
It is, however, hard to modulate and control the speed on the interstate. Seems that there is a very sensitive point in which the turbo will spool and the car will take off seemingly jumping from 70 to 75+ with no real effort. Cruise control is required on the interstate.

(There aren't yet really any common places for the 1.0 Ecoboost owners, not even a section on this forum....)
