I have 1.6 std ver of this car.. there are some good’s and bad’s about this cargood thing is its shape , styling and interiors.. the bad things are 1.mileage-i get a mileage of 9 kmpl -mixture of highway and city and whatever speed u ride its the same, i have tried driving less than 2000 rpm-no good. and the fuel sensor got changed in 6000 kms2.another thing is its discomfort in normal (unrubberrised) roads.. I live in suburbs where the roads are normal but unrubberised and its like going in a horse back when goin. v had a honda city earlier which ws 100 times better than this regarding this issue.. its the same regardless of the speed and the front and rear seats.. it seems like its a known issue with optra’s and its very much discomfort to travel in a car which gives same comfort as maruthi as costly as 8 lacs.3.visiting GM showroom has never been a good experince for me.. have gone there manytimes for differnt reasons.. but no much CSAT and promises are like gone in air.
