Well you have four options in the Petrol Hatch Category.
Chevy UV-A
Swift Vxi
Getz Prime GLS
Hyundai i10
Regards the Chevy UV-A its an allround great car with no real negatives except the GM After sales/service and probably the resale value. GM is here to stay and if you plan to keep the car for a minimun of 4-5 years do take test ride, i see no reason why GM badge should be too much of an issue.
Swift VXI - I guess you pretty much covered everything in ur own report. Again a decent all round car.
Getz GLS - The car to go for if you can stretch your budget and SPACE and Quality built are your priority. It has the 1.3 engine. If u have to haul 4-5 well built indians in comfort this is it!
Hyundai i10 - Have u checked it out???

All the best for your decision and do let us all know what you go for
