Sail Uva Review

Not happy with the purchase, totally cheated by the people out their. Not giving any fuel relaxation. I have driven around 4k kms and spent money like water on fuel. the people out their claim around 21km and promise to deliver around 18km, however got it serviced 3 times still hard to get.And that too on finance, totally lost with mind and senses.
Can somebody help.......?

Even after making visits 4 times in the last 2 months I am still at the same point. The asked me to drive at 5th gear above 50 to get the maximum output but unfortunately its still the same and lost the pleasure of power too.
May be thats the reason this is not on the roads visible so often. I have hardly seen 4-5 max on the roads lesser than in their showrooms even. And their is no marketing or advertising too, probably they know its not a good product to be endorsed. I have totally lost my faith in General Motors
Seriously Guys, if you are planning a purchase dont experiment with your money and go with the trusted brands.
The service people try to help but there is no result
