Good car but lacks of basic features in starting model.

It's just 1 week buying this car. First of all Driving is a pleasure no regrets. Looks are awesome externally but interior is not worthy. No rear power windows at the cost of 8.80 lakhs. No basic stereo or speakers. Expensive top end model with features. Mileage is another issue 1.2 cc engine and average is just around 11 km/l not any near what company claims.. Build quality is good when compare to maruti cars.. Space is also good..
