Having done 25,000 miles a year for 3 years in a 1996 1.1l, 55 BHP Punto, I would imagine a 1.4 would present no trouble at all. Sure, the commute is much more relaxed with a 1.8l, 130 BHP engine at my disposal, but the little engine could do it.
Before anyone asks why a Punto owner is lurking in the Bravo forum, it's because I'm considering a Bravo next.
