alto LXI-BSlll

I've been using this car from 5 months crossed 1200kms. I bought this instead of Santro coz of milage. I knew it has less power, but didn't expected it to be so poor. 98% of time I'm alone even then feel the problem in pick up.
Initially it gave me good average of 18km/Ltr with AC but now I'm getting 14-16Km/ltr.
It hardly reaches speed above 115km/hr.  Braking is also not that efficient, seriously needs to be improved.
It needs frequent servicing , specially theCLUCHis very poor .... Overall I feel very disappointed................

good fuel economyproblem with braking,less pickup and bad interiors etc
