I have recently sold my Cervo Turbo 2008 / 2012. The only reason for selling it was its low fuel average. It was giving me 9-10 km/l. I did everything I could do, tuning, overall engine check, turbo check, but nothing changed it's average.
Sold it through Pakwheels for Rs. 13 lacs.
I have now bought Honda Zest Spark 2012 / 2015. It's average is between 18-19 km/l, sometimes 20. So I'm pretty much satisfied. Bought it for 15.7 lacs from a showroom.
