I have both cars for more than a year (2009 Civic auto and 2014 City auto). Following are the points I would put in:
Civic
Comfort / Room
Power / Driving Pleasure
Better handling
Looks (in my opinion of course)
City
Fuel Avg. 2-3 km per liter better than Civic (10 kmpl vs. 7-8 kmpl in city driving with AC)
Maintenance (only marginally cheaper than Civic)
Parking convenience (tighter spaces)
Of course the old vs. new points still remain, Civic is only an option if a genuine good condition car is available.
