I have a Getz GVS, the original Getz so to speak before Getz Prime was born, purchased in August, 2006. It has clocked about 25, 000 plus Km.
I must say the driving comfort/experience is excellent. Although the mileage, with A/C on in the city, is quite low (8-9 Km per Litre) and which is infact quite well known, you get a much better mileage on the highway (15 Km plus at the least if you drive properly/steadily).
Overall having been using it for 3 years, I would say it is a very good vehicle and the important thing is it looks way better than Maruti Swift.
Getzs looks are gorgeous compared to its competitor Swift and that alone should be reason enough for one to select Hyundai Getz over Maruti Swift.
