well i today completed first 500 kms on my city 2012.
1.FE-10.3 overall with full ac,never turned it off for continuous 1min.
2.scratched the underside 4-5 times on one steep speed breaker only.others it survived.
3.this model is noisy,at 50 if you put ac blower on 1 and music off you will hear engine sound clearly and after 2-3 mins it is irritating,you have to turn music on(<12).after you cross 80 mark then it again becomes irritating so you have to make the music louder.(>15).if you touch 100 then you will again hear the engine sound like a race car.this thing i din't appreciated much in my old 2011 city.
4.a.c is good with reference to the heat outside.
5.on not so good roads it feels like this car is somewhat loose and we should take a screw driver and make it tight.this thing again i din't noticed in previous one.
will be leaving for jaipur in next 2-3 days so thats a ~1000 km drive(to and fro),will tell about the experience,after returning.
